74AVC4T245

4-bit dual supply translating transceiver with configurable

voltage translation; 3-state

Rev. 6 — 20 March 2019 Product data sheet

1. General description

The 74AVC4T245 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

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.
