DS7837DS8837 Hex Unified Bus Receiver

General Description

The DS7837DS8837 are high speed receivers designed for

use in bus organized data transmission systems intercon-

nected by terminated 120X impedance lines The external

termination is intended to be 180X resistor from the bus to

bus to ground The receiver design employs a built-in input

hysteresis providing substantial noise immunity Low input

current allows up to 27 driverreceiver pairs to utilize a com-

mon bus Disable inputs provide time discrimination Disable

inputs and receiver outputs are TTL compatible Perform-

ance is optimized for systems with bus rise and fall times
