SN74LV74AQPWRQ1

Flip Flops Overview

The SN74LV74AQPWRQ1 is a dual D-type flip-flop designed for automotive applications, featuring positive-edge triggering and operation within a 2V to 5.5V VCC range. It incorporates Ioff support for partial power-down mode functionality, preventing destructive backflow currents when the device is de-energized. The component meets AEC-Q100 qualification standards, ensuring reliability in harsh environments with an operating temperature range of -40°C to +125°C. Packaged in a 14-TSSOP surface-mount format, it provides non-inverting outputs suitable for high-speed digital logic control.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation across all ports
• Includes Ioff circuitry to disable outputs during local power-down
• Provides ESD protection exceeding JESD 22 specifications

Flip Flops Applications

• Programmable Logic Controllers (PLC)
• DCS and PAC analog input modules
• AV receivers and set-top boxes
• Server motherboards and power supply units

Flip Flops Procurement Notes

Verify that the specific part number suffix matches the required package type and tape-and-reel configuration for your assembly line. Confirm AEC-Q100 grade compliance if automotive certification is mandatory. Check for any recent Product Change Notifications regarding manufacturing sites or material composition updates before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when dual independent D-type storage is required with wide voltage tolerance. The Ioff feature makes it ideal for systems requiring safe partial power-down states. Ensure the 14-TSSOP footprint aligns with PCB layout constraints. Consider propagation delay characteristics relative to system clock speeds for timing closure verification.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74LV series, which offers low-voltage CMOS performance. The 'Q1' suffix denotes automotive-grade qualification under AEC-Q100 standards. It serves as a robust alternative to standard commercial logic families in demanding industrial and vehicular electronic control units requiring high noise immunity and extended temperature ranges.

Flip Flops Replacement Considerations

SN74LV74A-Q1 is the commercial/industrial variant without automotive qualification. SN74LV74APWRQ1 may denote different packaging options within the same family. Verify pinout compatibility and electrical parameter equivalence before substituting.
