74AVC4T245-Q100
Rev. 5 — 17 March 2020
4-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Product data sheet
1. General description
The 74AVC4T245-Q100 is an 4-bit, dual supply transceiver that enables bidirectional level
translation. The device can be used as two 2-bit transceivers or as a 4-bit transceiver. It features
four 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), a output enable
input (nOE) 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 nAn, nOE and
nDIR are referenced to V
CC(A)
and pins nBn are referenced to V
CC(B)
. A HIGH on nDIR allows
transmission from nAn to nBn and a LOW on nDIR allows transmission from nBn to nAn. The
output enable input (nOE) 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 nAn and nBn
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.
