Overview
The MC74HC573ADWG, 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 and functionally similar to the HC373A but with the data inputs on the opposite side of the package from the outputs. This design facilitates easier PC board layout. The MC74HC573A is a high-performance silicon-gate CMOS device, making it compatible with standard CMOS outputs and, with pullup resistors, compatible with LSTTL outputs as well.
