DS89C386

Twelve Channel CMOS Differential Line Receiver

General Description

The DS89C386 is a high speed twelve channel CMOS dif-

ferential receiver that meets the requirements of TIA/EIA-

422-B. The DS89C386 features low power dissipation of 240

mW typical.

Each TRI-STATE

be active or in a Hi-impedance off state. Each enable is

common to only two receivers for flexibility and multiplexing

of receiver outputs.

The receiver output (RO) is guaranteed to be High when the

inputs are left open and unterminated. The receiver can

detect signals as low and including

mon mode range of

compatible with both TTL and CMOS levels.
