CONNECTION
DESCRIPTION 74LCXHR162245 voltage CMOS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate double-layer metal wiring C2MOS technology. ideal power high speed 3.3V applications; interfaced signal environment both inputs outputs. This intended two-way asynchronous communication between data buses; direction data transmission determined input. enable inputs used disable device that buses effectively isolated. hold data inputs provided order eliminate need external pull-up pull-down resistor. outputs, which designed sink 12mA, include resistors reduce overshoot undershoot. inputs outputs equipped with protection circuits against static discharge, giving them immunity transient excess voltage.
