General Description
The 74LCXZ245 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 74LCXZ245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. When VCC is between 0V and 1.5V, the 74LCXZ245 is on the high impedance state during power up or power down. This places the outputs in the high impedance (Z) state preventing intermittent low impedance loading or glitching in bus oriented applications.
