SN74LVC244ADWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244ADWRG4 is an octal buffer and line driver from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features eight non-inverting channels with independent output enable inputs. The device provides three-state outputs, supporting asynchronous communication between data buses. Key electrical parameters include a propagation delay of 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. It offers high-level and low-level output currents of -24 mA and 24 mA respectively, with a maximum operating temperature of +125 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the 1.65 V to 3.6 V operating voltage aligns with your system power rails. Check that the -40 °C to +125 °C temperature range satisfies your environmental conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low-voltage operation below 3.3 V is required compared to standard CMOS families. The LVC series offers faster switching speeds than HC/HCT counterparts while maintaining lower power consumption. The wide input voltage tolerance allows interfacing with 5 V systems despite lower supply voltages. Consider the SOIC-20 package for surface-mount assembly compatibility.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A series of octal buffers. It shares functional similarities with other LVC devices but is distinct from LVTH or AHC families regarding speed and voltage ranges. The 'G4' suffix typically denotes green/RoHS-compliant packaging variations within the same logical function.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC244ADW is the tube-packaged equivalent without the G4 suffix. SN74LVC244APWR is the TSSOP-20 package variant. CLVC244AQDWRG4Q1 is the automotive-grade version with AEC-Q100 qualification.
