MICROCIRCUIT DATA SHEET Original Creation Date: 09/17/98 Last Update Date: 03/09/99 Last Major Revision Date: 02/15/99 MN54LCX245-X REV 0A0 Low Voltage Octal Bidirectional Transceiver With 5V Tolerant Inputs and Outputs 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.
