SN74LV244AQWRKSRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244AQWRKSRQ1 is an automotive-grade octal buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features balanced CMOS 3-state outputs. The device is configured into two independent banks of four drivers, each controlled by its own active-low output enable pin. It supports mixed-mode voltage operation on all ports and includes Ioff circuitry for partial-power-down applications. The component is qualified under AEC-Q100 standards with a temperature grade of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and lead-free status. Confirm that the AEC-Q100 qualification aligns with the target automotive application requirements. Ensure the WRKS package variant is correctly identified for PCB layout purposes. Cross-reference the datasheet revision date to confirm the most current electrical specifications are being utilized.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-speed CMOS buffers in automotive environments requiring mixed-voltage compatibility. The dual-bank architecture allows independent control of signal paths. Consider the thermal resistance metrics if operating near maximum temperature limits. Verify that the capacitive load does not exceed recommended values to maintain signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A-Q1 family of octal buffers and drivers designed for automotive use. It shares functional similarities with standard logic buffers but includes enhanced reliability features such as latch-up performance exceeding 250 mA per JESD 17. The WRKS package provides a compact footprint suitable for space-constrained automotive electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV244ADWR is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 qualification.
