DS89C21TM/NOPB Description

Short technical summary and product information.

The DS89C21TM/NOPB from Texas Instruments is a differential CMOS line driver and receiver pair designed to meet TIA/EIA-422-A (RS-422) and CCITT V.11 standards. This transceiver offers a signaling rate of up to 20 Mbps, making it suitable for high-speed applications. It features a low power design with a typical supply current of 6 mA.

 

The device includes one driver and one receiver in a compact 8-pin SOIC package. The driver boasts a fast transition time of 2.2 ns and a maximum differential skew of 2.0 ns. The receiver can detect signals as low as 200 mV and incorporates hysteresis for noise rejection, with a maximum skew of 4.0 ns. It operates over a wide temperature range of -40°C to +85°C and is compatible with TTL and CMOS levels.

 

This transceiver is ideal for power-conscious applications due to its low power consumption. It supports both RS422 and RS485 protocols, offering full duplex communication. The surface mountable 8-SOIC package facilitates integration into various electronic designs.
