General Description
54LCX245 General Description
The LCX245 contains eight non-inverting bidirectional buffers with TRI-STATE™ outputs and is intended for bus oriented applications. The device is designed for low voltage (3.3V) VCC applications with capability of interfacing to a 5V signal environment. The T/R input determines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a high impedance state. The LCX245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
