Overview
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 id...
