Overview
The MC74HC573ADWR2G, produced by onsemi, is an Octal 3-State Noninverting Transparent Latch. This device is part of the HC573A series, which is identical in pinout to the LS573. It is designed to be compatible with standard CMOS outputs and, with the use of pullup resistors, can also interface with LSTTL outputs. The MC74HC573A appears transparent to data when the Latch Enable is high, and data is latched when the Latch Enable goes low, provided the setup and hold times are met. This component is particularly useful for facilitating PC board layout due to its configuration of data inputs on the opposite side of the package from the outputs.
