DS89C386

Twelve Channel CMOS Differential Line Receiver

General Description

Features

n Low power design — 240 mW typical

n Meets TIA/EIA-422-B (RS-422)

n Receiver OPEN input failsafe feature

n Guaranteed AC parameters:

The DS89C386 is a high speed twelve channel CMOS differ-

ential receiver that meets the requirements of TIA/

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

240 mW typical.

Each TRI-STATE^®enable, EN, allows the receiver output to

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

mon to only two receivers for flexibility and multiplexing of re-

ceiver outputs.

— Maximum receiver skew −4 ns

— Maximum transition time −9 ns

n High Output Drive Capability: 6 mA

n Available in SSOP packaging:

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

inputs are left open and unterminated. The receiver can de-

— Requires 30% less PCB space than 3 DS34C86TMs

tect signals as low and including 200 mV over the common

mode range of 7V. The receiver outputs (RO) are compat-

ible with both TTL and CMOS levels.
