The SN75C1167DBR is a high-performance interface transceiver designed by Texas Instruments (formerly Luminary Micro), specifically engineered for robust RS422 and RS485 communication protocols. This sophisticated integrated circuit addresses critical communication interface challenges in industrial and telecommunications environments by providing a compact, reliable half-duplex transceiver solution.
The device features a dual-channel design with two drivers and two receivers, enabling efficient bidirectional data transmission in challenging electromagnetic environments. Its 16-pin SSOP (Small Shrink Outline Package) ensures compact surface-mount installation, making it ideal for space-constrained electronic systems that require reliable serial communication interfaces.
Operating across a supply voltage range of 4.5V to 5.5V, the transceiver demonstrates remarkable performance characteristics, including a receiver hysteresis of 60mV that enhances signal integrity and noise immunity. The component is fully RoHS compliant and designed to function reliably within standard industrial temperature ranges from 0°C to 70°C.
Key advantages include its half-duplex capability, which allows bidirectional communication over a single bus, robust electrical characteristics supporting RS422 and RS485 standards, and low power consumption. The transceiver is particularly well-suited for industrial automation, telecommunications equipment, networking infrastructure, and embedded control systems requiring reliable, long-distance serial communication.
