SN74LVTH244APWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244APWRG4 is an octal buffer and line driver from Texas Instruments, utilizing the LVTH logic series. It features eight non-inverting channels with three-state outputs housed in a 20-TSSOP package. The device operates within a supply voltage range of 2.7V to 3.6V and supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a high-level output current of -32mA and a low-level output current of 64mA. Propagation delay is specified at 2.3ns when operating at 3.3V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight independent non-inverting buffer channels for parallel signal transmission
• Features three-state outputs that allow bus sharing and isolation by entering a high-impedance state
• Supports 5V tolerant inputs while operating on lower voltage supplies for mixed-voltage system compatibility

Buffers, Drivers, Receivers, Transceivers Applications

• Parallel data buffering in industrial control systems
• Signal driving for communication equipment backplanes
• Level translation between different voltage domains in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C commercial/industrial temperature range for reliable performance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring high-speed octal buffering with mixed-voltage input tolerance. It is suitable for applications needing strong drive capability (64mA sink) and low propagation delay. Consider the TSSOP-20 package constraints regarding thermal dissipation and board space compared to SOIC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A family of advanced low-voltage CMOS logic devices. The 'G4' suffix typically denotes lead-free and RoHS-compliant packaging variants produced by Texas Instruments. It serves as a successor or alternative to older ABT and LVT families, offering improved speed and power efficiency for modern digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH244ADWR and SN74LVTH244ADWG4 are functionally equivalent parts from the same manufacturer but utilize SOIC-20 packages instead of TSSOP-20. Verify pinout compatibility and physical footprint differences before substituting.
