They are specified in common to all latches. compliance with JEDEC standard no. When LE is HIGH, data at the D n 3-state inverting outputs for bus 7A. inputs enter the latches. In this oriented applications condition the latches are transparent, The 74HC/HCT563 are octal D-type Inputs and outputs on opposite i.e. a latch output will change state transparent latches featuring sides of package allowing easy each time its corresponding D-input separate D-type inputs for each latch interface with microprocessor changes. and inverting 3-state outputs for bus Common 3-state output enable oriented applications. When LE is LOW the latches store the input A latch enable (LE) input and an information that was present at the Output capability: bus driver output enable (OE) input are common D-inputs a set-up time preceding the to all latches.

GENERAL DESCRIPTION When OE is HIGH, the outputs go to The 563 consists of eight D-type the high impedance OFF-state. The 74HC/HCT563 are high-speed transparent latches with 3-state Operation of the OE input does not Si-gate CMOS devices and are pin inverting outputs.
