    PIN DESCRIPTIONS
    Host Interface Pins
    Serial Clock (SCL)
    The SCL input is used to clock data into and out of the
    X9429.
    Serial Data (SDA)
    SDA is a bidirectional pin used to transfer data into
    and out of the device. It is an open drain output and
    may be wire-ORed with any number of open drain or
    open collector outputs. An open drain output requires
    the use of a pull-up resistor. For selecting typical
    values, refer to the guidelines for calculating typical
    values on the bus pull-up resistors graph.
    Device Address (A
    0
    , A
    2
    , A
    3
    )
    The Address inputs are used to set the least
    significant 3 bits of the 8-bit slave address. A match in
    the slave address serial data stream must be made
    with the Address input in order to initiate
    communication with the X9429. A maximum of 8
    devices may occupy the 2-wire serial bus.
