74ALVCH16373 2.5 V/3.3 V 16-bit D-type transparent latch 3-state Rev. 8 22 November 2021 Product data sheet 1. General description The 74ALVCH16373 is a 16-bit D-type transparent latch with bus hold inputs and 3-state outputs. The device can be used as two 8-bit transparent latches or a single 16-bit transparent latch. The device features two latch enables (1LE and 2LE) and two output enables (1OE and 2OE), each controlling 8-bits. When nLE 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 nLE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of nLE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Operation of the nOE input does not affect the state of the latches. This device is fully specified for partial power down applications using I . The I circuitry disables OFF OFF the output, preventing the potentially damaging backflow current through the device when it is powered down. 2.
