SN74LVC244APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244APWR is an octal buffer and line driver manufactured by Texas Instruments, designed for operation with a supply voltage range of 1.65V to 3.6V. It features eight non-inverting channels organized into two independent four-bit sections, each controlled by a separate output enable (OE) input. The device provides three-state outputs capable of sourcing and sinking up to 24mA. It supports mixed-mode signal operations across all ports and includes IOFF functionality to prevent back-driving during partial power-down or live insertion scenarios.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operations allowing simultaneous analog and digital signaling on the same port
• Provides IOFF support to ensure high-impedance state during partial power-down or live insertion events
• Features independent output enable inputs to control data flow between A inputs and Y outputs

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Industrial equipment signal buffering
• Consumer electronics interface driving
• Wireless and imaging system signal processing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision level against the latest Texas Instruments datasheet to ensure compatibility with current design requirements. Confirm that the TSSOP-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental specifications of the final application. Check for any recent product change notifications regarding manufacturing sites or material composition updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low-voltage operation between 1.65V and 3.6V is required. Choose this part for applications needing high drive capability with 24mA output currents. Consider this device for systems requiring isolation during power transitions via its IOFF feature. Opt for this buffer when independent channel control via dual OE pins is necessary for bus management.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74LVC244A series within the broader LVC logic family. It serves as a standard octal buffer solution for low-voltage CMOS applications. The device complements other Texas Instruments logic products by providing reliable signal transmission in portable and battery-operated devices where power efficiency is critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC244ADW offers the same logical function in a SOIC-20 package. SN74LVCH244APWR provides similar performance with potentially different electrical characteristics. Verify pinout compatibility and voltage tolerances before substituting with alternative manufacturers' parts.
