SN74LVC244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244PWR is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes TSSOP-20 surface-mount packaging. The device contains eight non-inverting channels organized into two four-bit sections with independent output enable inputs. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. It supports mixed-mode signal operations across all ports and includes IOFF for partial power-down protection.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides octal buffering and driving capabilities with three-state outputs for bus-oriented communications
• Supports asynchronous communication between data buses through independent output enable controls
• Enables safe hot insertion via IOFF feature which prevents excessive current draw during partial power-down
• Accepts input voltages up to 5.5 V allowing compatibility with 5-V controlled signals while operating at lower voltages

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous data bus buffering in industrial control systems
• Signal driving in consumer electronics requiring low-voltage operation
• Wireless infrastructure equipment interface circuits
• Imaging and video processing signal routing
• Motor drive and control logic level translation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision suffix and tape-and-reel quantity against the manufacturer's latest ordering information. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the TSSOP-20 footprint matches your PCB design guidelines. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with low-voltage operation between 1.65 V and 3.6 V. It is suitable for applications needing mixed-mode signal handling and input tolerance up to 5.5 V. Consider propagation delay specifications relative to your system clock speeds. Evaluate thermal dissipation requirements based on load conditions and ambient temperature constraints within the -40 C to +125 C operating range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A family of octal buffers and drivers with three-state outputs. It shares functional similarities with other members like SN74LVC244ADW but differs in package type and reel configuration. The LVC series offers improved performance over standard LVC devices with faster switching speeds and lower power consumption. It serves as a key component in digital logic interfaces requiring reliable signal transmission across multiple lines simultaneously.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC244APWR is a direct replacement with identical functionality and pinout. SN74LVC244ADW provides the same electrical characteristics in a SOIC-20 package. SN74ALVC244PWRE4 offers faster propagation delays but requires verification of voltage compatibility. SN74LVCH244APWR is another alternative within the same family with similar features.
