SN74ALVC244DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC244DW is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V. The device is organized as two independent 4-bit drivers with separate output-enable inputs. It provides an output drive capability of ±24 mA at 3.3 V and achieves a maximum propagation delay of 2.8 ns at 3.3 V. The component is housed in a 20-pin SOIC (DW) package and supports an operating free-air temperature range from -40 °C to +85 °C.

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 input should be tied to VCC through a pullup resistor.

What are the ESD protection ratings?

The device features ESD protection exceeding JESD 22 standards, including 2000-V Human-Body Model, 200-V Machine Model, and 1000-V Charged-Device Model ratings.
