    Low Voltage Octal Bidirectional Transceiver with
    3-STATE Inputs/Outputs and 25 Series Resistors
    in the B Port Outputs
    General Description
    The LVT2245 and LVTH2245 contain eight non-inverting
    bidirectional buffers with 3-STATE outputs and are
    intended for bus-oriented applications. The Transmit/
    Receive (T/R) input determines the direction of data flow
    through the bidirectional transceiver. Transmit (active-
    HIGH) enables data from A Ports to B Ports; Receive
    (active-LOW) enables data from B Ports to A Ports. The
    Output Enable input, when HIGH, disables both A and B
    Ports by placing them in a high impedance state. The
    equivalent 25
    :
    -series resistor in the B Port helps reduce
    output overshoot and undershoot.
    The LVTH2245 data inputs include bushold, eliminating the
    need for external pull-up resistors to hold unused inputs.
    These transceivers are designed for low voltage (3.3V)
    V
    CC
    applications, but with the capability to provide a TTL
    interface to a 5V environment. The LVT2245 and
    LVTH2245 are fabricated with an advanced BiCMOS tech-
    nology to achieve high speed operation similar to 5V ABT
    while maintaining low power dissipation.
