SN74LV244ATDBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ATDBR is an octal buffer/driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features TTL-voltage compatible inputs and includes Ioff circuitry to support partial-power-down mode, preventing damaging current backflow. It is housed in a 20-pin SSOP (DB) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the SSOP-20 package when sourcing. Confirm that the operating environment strictly adheres to the 4.5 V to 5.5 V supply voltage limits. Ensure design safeguards account for the specified latch-up performance exceeding 250 mA per JESD 17 standards during procurement validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 5 V logic buffering with high-density integration. The SN74LV244ATDBR is suitable where mixed-mode voltage operation and partial-power-down capabilities are required. Verify that the SSOP package dimensions fit the target PCB layout constraints before finalizing the selection.
