SN74LVC244AQPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244AQPWRQ1 is an automotive-grade octal buffer and line driver from Texas Instruments, belonging to the LVC logic family. It features eight non-inverting inputs with three-state outputs controlled by two independent output enable (OE) pins. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical specifications include a maximum propagation delay of 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. Output drive capabilities are specified as -24 mA for high-level and 24 mA for low-level currents. Static current is typically 1 uA, with a maximum operating temperature of +125°C. It is housed in a TSSOP-20 package and holds AEC-Q100 qualification.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including suffixes such as 'G4' or specific tape-and-reel quantities when ordering. Confirm that the AEC-Q100 grade matches the specific reliability requirements of the target automotive application. Check for RoHS compliance status and ensure the TSSOP-20 package variant aligns with PCB footprint designs. Validate lead times and availability through authorized distributors to prevent production delays.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for automotive environments requiring robust logic buffering at low voltages. Compare against standard industrial grades if higher temperature stability above 125°C is needed. Consider the LVC family's compatibility with 3.3 V and 2.5 V logic levels. Evaluate pin count and package size constraints against alternative octal drivers like the SN74AHCT series if 5 V operation is required instead of low voltage.

Buffers, Drivers, Receivers, Transceivers Part Context
