    74LCXZ245
    Low Voltage Bidirectional Transceiver
    with 5V Tolerant Inputs and Outputs
    General Description
    The 74LCXZ245 contains eight non-inverting bidirectional
    buffers with 3-STATE outputs and is intended for bus ori-
    ented applications. The device is designed for low voltage
    (2.5V and 3.3V) V
    CC
    applications with capability of interfac-
    ing 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 maintain-
    ing CMOS low power dissipation. When V
    CC
    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.

    Note 1:
    To ensure the high-impedance state during power up or down, OE
    should be tied to V
    CC
    through a pull-up resistor: the minimum value or the
    resistor is determined by the current-sourcing capability of the driver.
