SN74LV244APWRG3

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244APWRG3 is an octal buffer and line driver from Texas Instruments, belonging to the LV logic series. 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. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 5 V and robust ESD protection exceeding JESD 22 standards. It supports mixed-mode operation and includes Ioff circuitry for partial power-down mode compatibility.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration with independent output enable controls for two groups of four bits each
• Three-state outputs designed for direct interface to bus systems
• Supports mixed-mode operation allowing 5-V tolerant inputs with lower voltage supplies
• Ioff circuitry prevents excessive current draw during partial power-down states

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G3 suffix indicates lead-free and RoHS compliance per Texas Instruments specifications. Confirm the TSSOP-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets system requirements. Cross-reference the datasheet revision date to confirm parameter validity. Validate that the 2 V to 5.5 V supply range aligns with the target application voltage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for bus interfacing. The wide 2 V to 5.5 V supply range offers flexibility for various logic families. The LV series provides high speed with low power consumption. Consider the TSSOP-20 package for space-constrained surface-mount designs. Verify input voltage tolerance if interfacing with 5-V signals while powered by lower voltages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of octal buffers and drivers. The 'PWR' designation specifies the TSSOP-20 surface-mount package. The 'G3' suffix typically denotes lead-free packaging and RoHS compliance. It is functionally similar to other octal buffers but optimized for low-voltage applications. The device is part of Texas Instruments' broader standard logic portfolio.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV244APWR is the non-RoHS equivalent with identical electrical performance and pinout. SN74LVC244APWR offers similar functionality but operates on a narrower 1.65 V to 3.6 V supply range. SN74LVTH244APWR provides higher drive strength but requires a stricter 2.7 V to 3.6 V supply. Verify package compatibility and voltage tolerances before substitution.
