SN74LV244ADWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADWG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74LV logic family. It features non-inverting outputs with three-state control, organized into two independent four-bit sections. The device operates within a wide supply voltage range of 2V to 5.5V and supports mixed-mode voltage operations across all ports. It utilizes CMOS technology and is housed in a 20-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 6.5ns at 5V, high output drive capability of 16mA, and robust ESD protection exceeding 2000V human model standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance. Confirm the DW package designation corresponds to the standard 20-SOIC form factor. Ensure the ordering part number matches the specific tape-and-reel or tube packaging requirements for your assembly process. Cross-reference the manufacturer's latest datasheet for any pinout revisions or environmental certification updates prior to final procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2V and 5.5V rails. It is suitable for applications needing high-speed buffering with minimal propagation delay. Consider the three-state output feature for bus sharing scenarios. Evaluate the thermal performance within the -40°C to 125°C operating range for industrial environments. Compare against LVTH series if higher drive currents are required at lower voltages.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the SN74LV244A family of octal buffers. The ADWG4 variant specifically denotes the SOIC package with green (RoHS-compliant) manufacturing. It serves as a direct replacement for older LS or ALS logic families where lower power consumption and wider voltage ranges are beneficial. The G4 suffix typically signifies lead-free material composition and adherence to specific environmental directives.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV244ADWR is a functionally equivalent alternative available in a tape-and-reel package. Verify that the pinout remains identical when substituting with other 74LV244 variants from different manufacturers. Ensure that the replacement part maintains the same three-state control logic and voltage tolerance specifications.
