概述

The T74V4T774 device is a 4-bit level shifter, with an enable (OE) input and can work within the V_CCA range from 0.8 V to 3.6 V and the V_CCB range from 0.8 V to 3.6 V.

The T74V4T774 enables asynchronous communication between data buses. Depending on the logic level of the direction control (DIRn) input, this device transmits data either from the A bus to the B bus or from the B bus to the A bus. The output enable (OE) pin can be used to disable the outputs, effectively isolating the buses.

The enable control pin (OE) and direction control pin (DIRn) of the T74V4T774 are powered by V_CCA.

The T74V4T774 fully complies with the specifications for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging backflow current through the device when it is powered down.

For high-impedance operation during power-up/powerdown conditions, the OE (output enable) pin must be tied to V_CCA via a pull-up resistor. The minimum resistor value depends on the sink current capability of the driver.

The T74V4T774 is available in the QFN1.8X2.6-16 package and is characterized from −40°C to +125°C.
