SN74LVC2244APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2244APWR is a Texas Instruments buffer and line driver featuring two non-inverting 4-bit channels in a 20-TSSOP package. It operates within a supply voltage range of 1.65V to 3.6V, supporting mixed-mode signal operations across all ports. The device provides tri-state outputs with independent output enable inputs for each channel. It offers high noise immunity and supports hot insertion via IOFF circuitry. The component is designed for asynchronous communication between data buses and ensures high-impedance states during power-up or power-down conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-20 package and tape-and-reel shipping configuration. Ensure the 'A' designation aligns with the required temperature grade and performance specifications for your design. Confirm RoHS compliance status matches current regulatory requirements for your target market before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual 4-bit buffers with independent control in a compact surface-mount package. It is suitable for applications needing mixed-signal operation and hot-insertion capabilities. Consider the 1.65V to 3.6V operating range to ensure compatibility with low-voltage logic families. Verify that the 20-TSSOP footprint fits your PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2244A series of octal bus transceivers organized as two 4-bit sections. It is part of Texas Instruments' broader LVC logic family, which focuses on low-voltage, high-speed CMOS technology.
