4-bit dual supply translating transceiver with configurable

voltage translation; 3-state

Rev. 2 — 17 December 2015

Product data sheet

1. General description

The 74AVCH4T245-Q100 is a 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 two 2-bit input-output ports (nAn and nBn), a direction control input

(nDIR), an output enable input (nOE) and dual supply pins (V_CC(A)and V_CC(B)). Both

_CC(A)and V_CC(B)can be supplied with any voltage between 0.8 V and 3.6 V. This feature

makes 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 outputs are in the high-impedance OFF-state. The bus hold

circuitry on the powered-up side always stays active.

The 74AVCH4T245-Q100 has active bus hold circuitry which is provided to hold unused

or floating data inputs at a valid logic level. This feature eliminates the need for external

pull-up or pull-down resistors.

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
