GENERAL DESCRIPTION

The 74AVC4T245Q is a 4-bit, dual-supply voltage level

transceiver with 3-state outputs and bidirectional level

translation. The device can be used as two 2-bit

transceivers or one 4-bit transceiver. The nAn and nBn

are four data input-output ports. nDIR are the direction

control inputs and nOE????? are the output enable inputs.

VCCA and VCCB are the supply pins. The supply voltage of

VCCA and VCCB can range from 0.8V to 3.6V, making the

device suitable for bidirectional translating among any of

the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V voltage nodes.

The nAn, nDIR and nOE????? signals are referenced to VCCA

and nBn signals are referenced to VCCB.

When nDIR is set high, it allows transmission from nAn

to nBn. When nDIR is set low, it allows transmission

from nBn to nAn. n?

OE???? can be used to make the

outputs disabled so that the buses are effectively

isolated. In suspend mode, both nAn and nBn are in

high-impedance state when either VCCA or VCCB input is

at GND level.

This device is highly suitable for partial power-down

applications by using power-off leakage current (IOFF)

circuit. When the device is powered down, the outputs

are disabled, and the current backflow can be

prevented from passing through the device.

The device is AEC-Q100 qualified (Automotive

Electronics Council (AEC) standard Q100 Grade 1) and

it is suitable for automotive applications.

The 74AVC4T245Q is available in Green TSSOP-16,

TQFN-3.5×4-16L and TQFN-2.5×3.5-16L packages. It

operates over an operating temperature range of -40℃

to +125℃.
