Overview
The MC74LCX16245DTRG is a high-performance, non-inverting 16-bit transceiver designed by onsemi. This device operates from a supply voltage range of 2.3 to 3.6V and is byte controlled, allowing each byte to have separate Output Enable inputs that can be tied together for full 16-bit operation. It features high impedance TTL compatible inputs and TTL compatible outputs, which reduce current loading and improve switching noise performance. The device is suitable for memory address driving and all TTL level bus-oriented transceiver applications.
