Description

   The 74LCX32245 contains thirty-two non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device 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 32-bit operation. The T/R inputs of the 74LCX32245 determine the direction of data flow through the 74LCX32245. The OE inputs disable both the A and B ports by placing them in a high impedance state.

   The 74LCX32245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
