General DescriptionThe DS8838isa quad high speed driver/receiver designed
foruse inbusorganized data transmission systems intercon-
nectedby terminated 120Ω impedance lines.The external
terminationis intendedtobe 180Ω resistor fromthebusto
the +5V logic supply together witha 390Ω resistor fromthe
busto ground. Thebuscanbe terminatedatoneor both
ends. Low buspin current allowsupto27 driver/receiver
pairsto utilizea common bus. Thebusloadingis unchanged
when VCC=0V. The receivers incorporate hysteresisto
greatly enhancebus noise immunity. One two-input NOR
gateis includedto disableall driversina package simulta-
neously. Receiver performanceis optimizedforsystemswith
busriseandfall times≤1.0 μs/V.
