Product Summary

The 74LCX16245MEA contains sixteen non-inverting bidirectional buffer with 3-STATE outputs and is intended for bus oriented applications. The 74LCX16245MEA is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the 74LCX16245MEA. The OE inputs disable both the A and B ports by placing them in a high impedance state. The 74LCX16245MEA is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
