74ABT162245A; 74ABTH162245A

16-bit bus transceiver with 30 Ω series termination resistors; 3-state

The 74ABT162245A; 74ABTH162245A is a 16-bit transceiver with 30 Ω termination resistors and 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. This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Two options are available, 74ABT162245A which does not have the bus hold feature and the 74ABTH162245A which incorporates the bus hold feature.
