概述

The T74L8T245 device is an 8-bit level shifter that supports only Push-Pull mode, which operates with an enable (OE) input. it can work within the V_CCA range from 1.65 V to 5.5 V and the V_CCB range from 1.65 V to 5.5 V.

The T74L8T245 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 T74L8T245 are powered by V_CCA.

The T74L8T245 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/power-down conditions, the output enable (OE) 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 T74L8T245 is available in the TSSOP-24 package and is characterized from −40°C to +125°C.
