DS89C386 Twelve Channel CMOS Differential Line Receiver

Check for Samples: DS89C386

FEATURES

DESCRIPTION

The DS89C386 is a high speed twelve channel

CMOS differential receiver that meets the

requirements of TIA/EIA-422-B. The DS89C386

features low power dissipation of 240 mW typical.

•

Low Power Design—240 mW Typical

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

Receiver OPEN Input Failsafe Feature

Ensured AC Parameters:

Each TRI-STATE enable, EN, allows the receiver

output to be active or in a Hi-impedance off state.

Each enable is common to only two receivers for

flexibility and multiplexing of receiver outputs.

–

Maximum Receiver Skew −4 ns

Maximum Transition Time −9 ns

•

High Output Drive Capability: ±6 mA

Available in SSOP Packaging:

The receiver output (RO) is ensured to be High when

the inputs are left open and unterminated. The

receiver can detect signals as low and including ±200

mV over the common mode range of ±7V. The

receiver outputs (RO) are compatible with both TTL

and CMOS levels.

–

Requires 30% less PCB Space than 3

DS34C86TMs

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
