DS7837 DS8837 Hex Unified Bus Receiver
General Description
The DS7837 DS8837 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
the a5V logic supply together with a 390X resistor from the
bus to ground The receiver design employs a built-in input
hysteresis providing substantial noise immunity Low input
current allows up to 27 driver receiver 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
s1 0 ms V
Features
Y Low receiver input current for normal VCC or VCC e 0V
(15 mA typ)
Y Six separate receivers per package
Y Built-in receiver input hysteresis (1V typ)
Y High receiver noise immunity (2V typ)
Y Temperature insensitive receiver input thresholds track
bus logic levels
Y TTL compatible disable and output
Y Molded or cavity dual-in-line or flat package
Y High speed
