Overview
The MC74LCX16245DTR2G 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 byte controlled, with each byte having 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 transceiver is suitable for memory address driving and all TTL level bus-oriented transceiver applications.
