DS89C21 - Differential CMOS Line Driver and Receiver Pair

General Description

The DS89C21 is a differential CMOS line driver and receiver pair, designed to meet the requirements of TIA/EIA-422-A (RS-422) electrical characteristics interface standard.

The DS89C21 provides one driver and one receiver in a minimum footprint.

The device is offered in an 8-pin SOIC package.

Key Features

  • a fast transition time specified at 2.2 ns, and a maximum differential skew of 2 ns making the driver ideal for use in high speed.

DS89C21 Differential CMOS Line Driver and Receiver Pair June 1998 DS89C21 Differential CMOS Line Driver and Receiver Pair General Description The DS89C21 is a differential CMOS line driver and receiver pair, designed to meet the requirements of TIA/EIA-422-A (RS-422) electrical characteristics interface standard. The DS89C21 provides one driver and one receiver in a minimum footprint. The device is offered in an 8-pin SOIC package. The CMOS design minimizes the supply current to 6 mA, making the device ideal for use in battery powered or power conscious applications. The driver features a fast transition time specified at 2.2 ns, and a maximum differential skew of 2 ns making the driver ideal for use in high speed applications operating above 10 MHz.
