16-bit bus transceiver with 30 Ω series termination resistors;
3-state
Rev. 5 — 2 July 2021
Product data sheet
1. General description
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 IOFF. The IOFF 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.
2. Features and benefits

[1] Valid for data inputs of bus hold parts only (74ABTH162245A)
[2] This is the bus hold overdrive current required to force the input to the opposite logic state.
[3] This parameter is valid for any VCC between 0 V and 2.1 V with a transition time of up to 10 ms.
From VCC = 2.1 V to VCC = 4.5 V to 5.5 V a transition time of 100 μs is permitted.
[4] Not more than one output should be tested at a time and the duration of the test should not exceed one second
[5] This is the increase in supply current for each input at 3.4 V.
