Overview
The MC74LCX16373DTR2 is a high-performance, non-inverting 16-bit transparent latch produced by onsemi. This device operates from a supply voltage range of 2.3 to 3.6V and is byte controlled, with each byte having separate Output Enable and Latch Enable inputs. These control pins can be tied together for full 16-bit operation. The MC74LCX16373DTR2 features high impedance TTL compatible inputs and TTL compatible outputs, which significantly reduce current loading to input drivers and offer improved switching noise performance. The device is also 5V tolerant, allowing it to be safely driven from 5V devices.
