SN74LVC244APWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244APWRG4 is an octal buffer and line driver from the Texas Instruments LVC logic family, housed in a 20-pin TSSOP package. It operates within a supply voltage range of 1.65 V to 3.6 V. The device features eight non-inverting channels organized as two independent 4-bit buffers with separate output enable inputs. Key electrical specifications include a maximum propagation delay of 6.7 ns at 2.7 V and 5.9 ns at 3.3 V. Output drive capability is rated at 24 mA for both high and low states, with a typical quiescent current of 1 uA. It supports mixed-mode signal operation across all ports.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports real-time insertion and partial power-down modes via IOFF functionality
• Enables downward voltage translation for interfacing different logic levels
• Accepts input voltages up to 5.5 V while operating on lower supply rails

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Industrial control systems
• Wireless infrastructure equipment
• Imaging and video signal processing circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance status according to current manufacturer documentation. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +125°C aligns with your environmental design constraints before finalizing component selection.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low-power CMOS performance is required for 1.8 V or 3.3 V systems. The LVC series offers faster switching speeds compared to standard LVC variants while maintaining low static power consumption. Consider the 24 mA drive strength for moderate capacitive loads without external buffering.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A family of octal buffers. It serves as a direct replacement for the SN74LVC244APWR, with the G4 suffix denoting specific manufacturing and environmental compliance attributes defined by Texas Instruments. It shares functional compatibility with other members of the LVC logic family.
