DS8838
Quad Unified Bus Transceiver
General Description
The DS8838 is a quad high speed driver/receiver designed
for use in bus organized data transmission systems intercon-
nected by terminated 120
termination is intended to be 180
the +5V logic supply together with a 390
bus to ground. The bus can be terminated at one or both
ends. Low bus pin current allows up to 27 driver/receiver
pairs to utilize a common bus. The bus loading is unchanged
when V
greatly enhance bus noise immunity. One two-input NOR
gate is included to disable all drivers in a package simulta-
neously. Receiver performance is optimized for systems with
bus rise and fall times
