1. General description
The 74ALVT162245 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.
