74LCX245MTCX - Fairchild Semiconductor - Low Voltage Bidirectional Transceiver with 5V Tolerant Inpu



Detailed Product Description

Quick Detail:


Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs and Outputs





The LCX245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low voltage (2.5V and 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.
