Overview
The MC74LCX573DTR2G is a high-performance, non-inverting octal transparent latch produced by onsemi. This component operates from a 2.3 to 3.6V supply and features high impedance TTL compatible inputs, which significantly reduce current loading to input drivers. The TTL compatible outputs offer improved switching noise performance. The device is 5V tolerant, allowing its inputs to be safely driven from 5V devices.
The MC74LCX573 contains 8 D-type latches with 3-state standard outputs. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches, making them transparent. When LE is LOW, the latches store the information present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-state standard outputs are controlled by the Output Enable (OE) input.
