SN74LV244ADBRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADBRE4 is an octal buffer and line driver from Texas Instruments, belonging to the LV logic series. It features eight non-inverting inputs with three-state outputs, organized into two independent four-bit groups controlled by separate output enable (OE) pins. The device operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode operation across all ports. It utilizes CMOS technology for low power consumption and high noise immunity. The component is housed in a 20-pin SSOP package and is designed for applications requiring bus driving, memory address buffering, and clock distribution.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS adherence during procurement. Confirm the SSOP-20 package variant matches the target PCB footprint. Ensure the operating temperature range aligns with industrial or commercial requirements. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision status before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2 V and 5.5 V domains. It is suitable for replacing older LS or ALS logic families where lower power consumption and higher speed are needed. Consider its three-state capability for multiplexed bus architectures. Evaluate the SSOP package constraints regarding thermal dissipation and board space availability compared to SOIC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SN74LV244A family of octal buffers. It shares functional similarities with the SN74LV244ADW but differs in packaging and environmental compliance specifications. The LV series is characterized by low voltage operation and improved switching speeds compared to legacy TTL technologies. It serves as a critical interface component in mixed-voltage digital environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV244ADWR is a functionally equivalent alternative available from the same manufacturer. Verify pinout compatibility and electrical characteristics before substitution. Ensure any replacement maintains the required three-state output functionality and voltage tolerance levels.
