SN74LVC244APWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244APWE4 is an octal buffer and line driver from Texas Instruments, belonging to the LVC logic family. It features eight non-inverting channels with three-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. The device supports mixed-mode signal operations, allowing 5-V tolerant inputs while powered by lower voltages. Key electrical characteristics include a maximum low-level output current of 24 mA and a high-level output current of -24 mA. It operates reliably across a temperature range of -40°C to +85°C and is housed in a TSSOP-20 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the package type matches the required PCB footprint, typically TSSOP-20 for this variant. Ensure input voltage levels do not exceed the absolute maximum ratings to maintain device integrity. Cross-reference the datasheet for specific thermal dissipation requirements under intended load conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when eight independent buffered channels are required for low-voltage digital interfaces. The LVC series offers a balance of speed and power consumption suitable for portable devices. Consider the 5-V tolerance feature if interfacing with legacy 5-V logic without level shifting. Evaluate the propagation delay specifications against system timing constraints to ensure signal integrity at operating frequencies.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A family of octal buffers. It is functionally similar to other variants like SN74LVC244ADWG4 but differs in package style and manufacturing revisions. The LVC series is widely used in modern digital designs requiring low power and high density. It serves as a standard solution for expanding drive capability on microcontroller buses or peripheral interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC244ADWR is a comparable SOIC-20 variant with identical logical functionality. SN74LVC244APWR is the non-RoHS version of the same TSSOP-20 package. Verify pin compatibility and electrical parameters before substituting any alternative buffer IC.
