SN74LV244AMDWREP

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244AMDWREP is an enhanced product octal buffer and driver manufactured by Texas Instruments. It utilizes CMOS technology to provide eight non-inverting channels, organized as two independent four-bit groups with separate three-state output enable controls. The device operates within a wide voltage range of 2 V to 5.5 V and supports mixed-mode voltage operations across all ports. It features robust ESD protection exceeding JESD 22 standards, including 2000-V human body model ratings. The component is housed in a 20-pin SOIC (DW) package and is rated for an extended operating temperature range from -55°C to 125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific 'A' suffix and 'REP' designation during procurement to ensure the component meets enhanced product specifications. Confirm that the 20-SOIC package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the supply chain source is authorized to guarantee the authenticity of the enhanced product grade.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when standard logic devices do not meet the required temperature or reliability thresholds. The wide 2 V to 5.5 V supply range allows compatibility with various logic families. The three-state outputs facilitate efficient bus sharing in complex digital architectures. Consider the 20-SOIC package size for space-constrained designs requiring through-hole or surface-mount flexibility depending on the specific variant availability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of octal buffers and drivers. The 'EP' suffix indicates it is an Enhanced Product, typically offering higher reliability metrics than standard commercial grades. It shares functional similarities with the SN74LV244ADW but differs in manufacturing lot controls and testing rigor. The device is distinct from automotive-qualified variants like the SN74LV244A-Q1, which follow AEC-Q100 standards.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV244ADW is a functionally equivalent standard commercial grade replacement. Verify that the reduced temperature range of the standard part (-40°C to 125°C) is acceptable for the application environment before substitution.
