SN74LV244APWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244APWRE4 is an octal buffer and line driver from the Texas Instruments 74LV logic family. It features eight non-inverting channels with three-state outputs, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode operation across all ports. It includes independent output enable inputs for each group of four drivers. The component is designed for high-density applications such as memory address drivers and clock distribution.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage operation allowing different input and output voltage levels on all ports
• Includes Ioff circuitry to support partial power-down mode operation
• Provides enhanced electrostatic discharge protection exceeding standard requirements

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the E4 suffix indicates lead-free construction compliant with RoHS standards. Confirm the TSSOP-20 package dimensions match the design footprint. Ensure the operating temperature range meets system requirements. Check for specific automotive or industrial qualification if required by the application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low voltage operation down to 2 V is required alongside 5 V compatibility. The three-state output allows direct connection to bus structures without external pull-ups. Verify that the propagation delay characteristics meet the timing constraints of the target digital interface.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A series of octal buffers. The E4 suffix denotes a lead-free variant manufactured by Texas Instruments. It shares functional specifications with the SN74LV244APWR but differs in material composition and environmental compliance certifications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV244APWR is a functionally equivalent alternative with identical electrical specifications. Other variants in the LV series may offer different packaging options while maintaining the same logical functionality.
