Overview
The MC74LCX16245DTR2 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 byte-controlled operation. Each byte has separate Output Enable inputs, which can be tied together for full 16-bit operation. The transceiver features high impedance TTL compatible inputs and TTL compatible outputs, reducing current loading and improving switching noise performance. It is suitable for memory address driving and all TTL level bus-oriented transceiver applications.
