SN74LVC244ADWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244ADWRE4 is an octal buffer and line driver from Texas Instruments' LVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features non-inverting, three-state outputs. The device provides high drive capability with output currents of ±24 mA. It supports mixed-mode operation, allowing 5-V tolerant inputs while powered by lower voltages. Key electrical characteristics include a propagation delay of 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. It functions reliably across an extended temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'RE4' against the manufacturer's official documentation to confirm it denotes lead-free status and tape-and-reel packaging. Ensure the order matches the exact part number to avoid confusion with tube-packaged variants like the DW suffix. Cross-reference RoHS compliance details directly with the datasheet before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing low-voltage systems requiring robust signal buffering between 1.65-V and 3.6-V domains. Its 5-V input tolerance makes it suitable for bridging older 5-V logic standards with modern low-power architectures. Consider the SOIC-20 package dimensions and thermal performance for your PCB layout constraints.
