Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

Can the SP3087EMN-L/TR be used in a 5V logic system with a 3.3V microcontroller, and what level-shifting considerations apply?
The SP3087EMN-L/TR is designed for bidirectional voltage translation between 1.65V and 5.5V on both sides, making it suitable for interfacing a 3.3V microcontroller to a 5V peripheral. However, the directionality and speed depend on pull-up resistors; ensure they are within the recommended range (typically 4.7kΩ) and that the slower side controls timing to avoid contention. Always verify signal integrity under worst-case capacitance loads.
What happens if I connect the A and B sides of the SP3087EMN-L/TR to supplies outside its 1.65V–5.5V operating range?
Operating the SP3087EMN-L/TR outside the 1.65V to 5.5V supply range on either side can lead to undefined output states, latch-up, or permanent damage due to excessive gate oxide stress. This applies even during power sequencing. Always adhere strictly to the absolute maximum ratings and ensure all supplies remain within this window throughout operation.
Is the SP3087EMN-L/TR suitable for hot-swapping applications where power rails may be connected asynchronously?
While the SP3087EMN-L/TR supports bidirectional communication, hot-swapping without proper current limiting or protection can still cause stress. Although it tolerates some overvoltage transients, repeated asynchronous connection of supplies beyond recommended slew rates may degrade reliability over time. Use series resistors and consider dedicated hot-swap controllers for critical applications.
How does the propagation delay of the SP3087EMN-L/TR affect high-speed I²C or SPI bus designs?
The typical propagation delay of 15 ns (max 30 ns) on the SP3087EMN-L/TR introduces minimal skew in most standard I²C systems running below 400 kHz. However, in high-speed modes (e.g., I²C at 3.4 Mbps), accumulated delays across multiple devices could violate setup/hold times. For such cases, evaluate total bus latency and consider faster translation ICs with sub-10 ns delays.
Can the SP3087EMN-L/TR replace a TXB0108 in an existing design with similar voltage levels?
The SP3087EMN-L/TR is functionally similar to the TXB0108 but differs in pinout and default enable configuration. Direct replacement requires verifying the enable pin behavior—SP3087EMN-L/TR has no explicit EN pin; instead, it uses direction sensing via internal circuitry. If your layout relies on external OE control, migration may require PCB modification. Also confirm package compatibility (SOP8 matches), but thermal performance may vary slightly.
What are the implications of using the SP3087EMN-L/TR in environments with significant electromagnetic interference?
As a digital translator, the SP3087EMN-L/TR offers limited immunity to EMI unless placed close to noise sources. Its small SOP8 package reduces loop area but increases susceptibility to fast transient bursts. To mitigate risk, use short traces, ground planes, and consider adding TVS diodes near connectors. Avoid routing high-impedance lines through noisy areas adjacent to the device.
Should I add decoupling capacitors when integrating the SP3087EMN-L/TR into a mixed-signal PCB?
Yes. Place a 0.1 µF ceramic capacitor as close as possible to each VCC pin of the SP3087EMN-L/TR to stabilize local power during switching transitions. This helps prevent oscillation and ensures reliable level shifting, especially under rapid data rate conditions or when driving capacitive loads.
Can the SP3087EMN-L/TR be powered from a single supply rail while translating between two different voltages?
No. The SP3087EMN-L/TR requires independent power supplies on both A and B sides. It does not support single-supply operation for bidirectional translation. Attempting to tie both sides to the same rail defeats the purpose and eliminates level-shifting capability. Each side must have its own regulated voltage within 1.65V–5.5V.
What is the maximum allowable capacitance load on the B-side of the SP3087EMN-L/TR before timing margins degrade?
The datasheet specifies a maximum B-side load capacitance of 50 pF. Exceeding this value increases propagation delay and rise/fall times, which can violate timing constraints in tight-clock systems. In practice, keep trace lengths short and minimize stubs. For loads above 20 pF, simulate or prototype to validate signal integrity.
Is the SP3087EMN-L/TR suitable for automotive-grade temperature ranges (-40°C to +125°C)?
The SP3087EMN-L/TR is rated for industrial temperature range (-40°C to +85°C). It is not qualified for automotive AEC-Q100 Grade 1 (up to +125°C). Using it in automotive applications outside this range may result in reduced lifetime, erratic behavior, or failure. For higher temperatures, select an automotive-qualified alternative with equivalent functionality.
