DESCRIPTIONThe 74VHC16245 is an advanced high-speedCMOS 16-BIT BUS TRANSCEIVER (3-STATE)fabricated with sub-micron silicon gate anddouble-layer metal wiring C2MOS technology.This IC is intended for two-way asynchronouscommunication between data busses; the direction of data transmission is determined byDIR input. The enable input G can be used todisable the device so that the busses areeffectively isolated.All inputs and outputs are equipped with protection circuits against static discharge, givingthem 2KV ESD immunity and transient excessvoltage.All floating bus terminals during High Z State mustbe held HIGH or LOW.
