Rev. 1 — 14 June 2019
2-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Product data sheet
1. General description
The 74AVC2T245-Q100 is a 2-bit, dual supply transceiver that enables bidirectional level
translation. The device can be used as two 1-bit transceivers or as a 2-bit transceiver. It features
two 2-bit input-output ports (An and Bn) and direction control inputs (DIRn), an output enable input
(OE) and dual supply pins (V
CC(A)
and V
CC(B)
). Both V
CC(A)
and V
CC(B)
can be supplied at any
voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low
voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins An, OE and DIRn are referenced
to V
CC(A)
and pins Bn are referenced to V
CC(B)
. A HIGH on DIRn allows transmission from An to Bn
and a LOW on DIRn allows transmission from Bn to An. The output enable input (OE) can be used
to disable the outputs so the buses are effectively isolated.
The device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry
disables the output, preventing any damaging backflow current through the device when it is
powered down. In suspend mode when either V
CC(A)
or V
CC(B)
are at GND level, both An and Bn
are in the high-impedance OFF-state.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
