SN74ALVC244RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC244RGYR is an octal buffer and line driver with three-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V. The device is organized as two independent 4-bit drivers, each featuring a separate output-enable (OE) input. When OE is low, data passes from the A inputs to the Y outputs; when OE is high, the outputs enter a high-impedance state. It provides a maximum propagation delay of 2.8 ns at 3.3 V and supports ±24 mA output drive current at 3.3 V. The component is housed in a 20-pin VQFN package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'RGYR' corresponds to the VQFN package and tape-and-reel quantity. Confirm RoHS compliance and moisture sensitivity level ratings against the latest Package Option Addendum. Ensure the operating temperature range meets system requirements. Check for any enhanced product variants if aerospace or medical applications are involved.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low-voltage operation between 1.65 V and 3.6 V. It is suitable for systems needing octal buffering with independent enable controls. Consider the VQFN package for space-constrained PCB layouts. Verify that the required output drive current does not exceed the specified limits for the target supply voltage.
