74LVCH162373A
description
The 74LVC162373A and 74LVCH162373A are 16-bit D-type transparent latches with 30 Ω termination resistors and 3-state outputs. The 74LVCH162373A has separate D-type inputs with bus hold for each latch. Both devices can be used as two 8-bit transparent latches or a single 16bit transparent latch. Both devices feature two latch enables (1LE and 2LE) and two output enables (1OE and 2OE), each controlling 8-bits. When n LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When n LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of n LE. A HIGH on n OE causes the outputs to assume a high-impedance OFF-state. Operation of the n OE input does not affect the state of the latches. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in...
