DS89C21TMX/NOPB Description

Short technical summary and product information.

The DS89C21TMX/NOPB from Texas Instruments is a versatile differential CMOS line driver and receiver pair. It is engineered to meet the stringent requirements of the TIA/EIA-422-A (RS-422) and CCITT V.11 electrical characteristics interface standards, making it suitable for robust serial communication.

 

This transceiver operates at a maximum signaling rate of 20 Mbps, with a low typical supply current of 6 mA, ideal for power-conscious applications. It features a driver with a maximum skew of 2.0 ns and a receiver with hysteresis for improved noise rejection and a maximum skew of 4.0 ns. The device supports a wide operating temperature range from -40°C to +85°C.

 

The DS89C21TMX/NOPB is supplied in an 8-pin SOIC package, designed for surface mounting. Its full duplex capability and compatibility with TTL and CMOS levels (DI and RO) enhance its integration into various system designs.
