Overview
The MC74LCX16245DT is a high-performance, non-inverting 16-bit transceiver produced by Onsemi. This device operates from a 2.3 to 3.6V supply and is designed for low-voltage applications with the capability to interface with 5V signal environments. It is byte-controlled, with each byte having separate Output Enable inputs that can be tied together for full 16-bit operation. The device features high impedance TTL compatible inputs and TTL compatible outputs, which reduce current loading and improve switching noise performance.
