They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT563 are octal D-type transparent latches featuring separate D-type inputs for each latch and inverting 3-state outputs for bus oriented applications. A latch enable (LE) input and an output enable (OE) input are common to all latches. The “563” is functionally identical to the “573”, but has inverted outputs. The “563” consists of eight D-type transparent latches with 3-state inverting outputs. The LE and OE are 74HC/HCT563 common to all latches. When LE is HIGH, data at the Dn inputs enter the latches. In this condition the latches are transparent, i.e. a latch ou……
