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 MM54C164J be used in a 5V industrial control system with mixed-voltage I/O interfaces, and what are the implications for signal conditioning at the input pins?
The MM54C164J is designed to operate from a single 5V power supply, making it suitable for 5V systems. However, when interfacing with higher or lower voltage signals, external level-shifting circuitry or clamping diodes may be required to prevent damage to the inputs, as the device does not inherently support voltages beyond its VCC rails.
Is the MM54C164J suitable for use in automotive environments where temperature cycling and long-term reliability are critical?
While the MM54C164J operates over a commercial temperature range, its standard military or extended temperature variants are not specified. For automotive-grade applications requiring -40°C to +125°C operation and high reliability, additional qualification testing or alternative parts with certified automotive ratings should be considered.
When replacing legacy 74164 shift registers with the MM54C164J in an existing design, what pin compatibility issues might arise due to package differences?
The MM54C164J uses a DIP-16 package, which matches the physical layout of many traditional 74164 devices. However, users must verify pin assignments for clock, clear, serial input, and parallel load functions, as some manufacturers vary these within the same package type.
Can the MM54C164J support synchronous parallel loading while also operating in shift mode without timing conflicts?
Yes, the MM54C164J supports asynchronous clear and synchronous parallel load independent of shifting. The parallel load function overrides shifting only during the active clock edge when the enable is asserted, allowing both modes to coexist safely with proper clock management.
What happens if the CLEAR pin on the MM54C164J is left unconnected during normal operation?
Leaving the CLEAR pin floating may result in unpredictable behavior, including potential unintended reset events due to noise pickup. It is recommended to tie the CLEAR input to VCC through a pull-up resistor or connect it directly to a stable logic high to ensure deterministic operation.
In a multi-device cascaded configuration using the MM54C164J, how should the serial output (QH) of one stage be connected to the next stage’s serial input (SER)?
The QH output of the first MM54C164J should be connected directly to the SER input of the subsequent stage. Care must be taken to maintain signal integrity by keeping traces short and avoiding excessive capacitance, which could degrade rise/fall times and cause timing violations.
Does the MM54C164J support hot-swapping or plugging into a powered circuit without risk of latch-up or damage?
No, the MM54C164J does not have built-in ESD protection or hot-swap tolerance. Inserting or removing the IC while the system is powered can lead to electrostatic discharge damage or transient current surges. External protection such as series resistors and TVS diodes is advised for robust handling.
Can the MM54C164J be used in a low-power battery-operated application where minimizing quiescent current is essential?
The MM54C164J has moderate power consumption typical of TTL-based shift registers. Its static power draw exceeds that of modern CMOS alternatives like the CD74HC164. Therefore, it is not ideal for ultra-low-power designs; a CMOS-compatible part should be selected instead.
What is the maximum propagation delay between the clock and data outputs when using the MM54C164J in high-speed data acquisition?
The typical propagation delay from clock to Q outputs is approximately 35 ns under standard 5V conditions. Designers must account for this latency when synchronizing multiple stages or meeting setup/hold requirements in real-time systems.
Are there any known compatibility issues when substituting the MM54C164J with newer CMOS equivalents like the CD74HC164 in legacy analog front-end designs?
While functionally similar, CMOS devices like the CD74HC164 have different input thresholds and drive characteristics compared to TTL-based MM54C164J. Direct substitution may require logic level translation, especially if driving legacy 5V TTL loads, and can affect noise margins in mixed-signal environments.
