SN74ALVC244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC244PWR is an octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V. The device features two independent 4-bit drivers, each with a separate output-enable (OE) input. At 3.3 V, the maximum propagation delay is 2.8 ns, with output drive capabilities of ±24 mA. It supports an operating temperature range of -40°C to +85°C and is housed in a TSSOP-20 package.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up states?

To ensure the outputs remain in a high-impedance state during power-up or power-down, the OE pin should be tied to VCC through a pullup resistor.

What is the input voltage tolerance?

The inputs are 5-V tolerant, allowing them to accept signals up to 5.5 V even when the device is powered by lower supply voltages.
