DS8641 - Quad Unified Bus Transceiver
The DS8641 is a quad high speed drivers/receivers designed for use in bus organized data transmission systems interconnected by terminated 120Ω impedance lines.
The external termination is intended to be a 180Ω resistor from the bus to the +5V logic supply together with a 390Ω resistor from the bus
DS8641 Features
* n 4 separate driver/receiver pairs per package n Guaranteed minimum bus noise immunity of 0.6V, 1.1V typ n Temperature insensitive receiver thresholds track bus logic levels n 30 µA typical bus terminal current with normal VCC or with VCC = 0V n Open collector driver output allows wire-OR connection
