General Description
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) V
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 tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
