1. General description

The 74LVT16245B; 74LVTH16245B is a 16-bit transceiver with 3-state outputs. The device can be

used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables

(1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for

direction control. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Bus

hold data inputs eliminate the need for external pull-up resistors to define unused inputs
