74VCX245: Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs

The VCX245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R# input determines the direction of data flow. The OE# input disables both the A and B ports by placing them in a high impedance state.     The 74VCX245 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V.     The 74VCX245 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation.
