SN74HCS174QPWRQ1

Flip Flops Overview

The SN74HCS174QPWRQ1 is an automotive-grade hex D-type flip-flop from Texas Instruments, designed for high-reliability applications. It features six positive-edge-triggered D-type flip-flops with independent clock inputs and active-low resets. The device operates within a supply voltage range of 2 V to 6 V, supporting a maximum clock frequency of 29 MHz. It exhibits a propagation delay of 15 ns and provides push-pull outputs with drive currents of ±7.8 mA. Packaged in a TSSOP-16 surface-mount format, it functions across an extended temperature range from -40°C to +125°C.

Flip Flops Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for long-term reliability
• Hex configuration providing six independent D-type flip-flops in a single package
• Wide operating voltage capability ranging from 2 V to 6 V for flexible system integration
• Schmitt-trigger inputs ensure noise immunity and clean signal transitions

Flip Flops Applications

• Automotive data acquisition systems requiring robust digital storage
• Vehicle control modules needing reliable state retention under varying temperatures
• Industrial automation interfaces utilizing wide voltage tolerance logic
• High-noise environments where Schmitt-trigger input filtering is critical

Flip Flops Procurement Notes

Verify the specific suffix QPWRQ1 matches the required automotive grade and TSSOP-16 package variant. Confirm that the manufacturer's datasheet specifies the exact electrical characteristics for your voltage and temperature conditions. Ensure compatibility with your board's thermal management requirements given the 125°C maximum operating limit. Cross-reference the component marking against official Texas Instruments identification guides to prevent counterfeit parts.

Flip Flops Selection Notes

Select this component when designing circuits that require multiple synchronized data storage elements within a constrained footprint. The HCS series offers superior noise immunity compared to standard HC logic due to its Schmitt-trigger inputs. Consider the 2 V to 6 V supply range if your system utilizes non-standard voltage rails or experiences significant voltage fluctuations. Evaluate the 15 ns propagation delay against your system's timing constraints to ensure adequate setup and hold times are met.

Flip Flops Part Context

This part belongs to the SN74HCS family, which combines high-speed CMOS performance with Schmitt-trigger functionality. Unlike the SN74HC174, the HCS variant includes hysteresis on all inputs to enhance noise rejection in electrically noisy environments. The 'Q1' suffix denotes automotive qualification, ensuring compliance with stringent reliability standards required for vehicle electronics manufacturing and deployment.

Flip Flops Replacement Considerations

Direct functional equivalents include the SN74HCS174N (DIP package) or SN74HCS174PW (TSSOP-16 without automotive grade). For non-automotive designs, the SN74HC174 series may be used but lacks Schmitt-trigger inputs. Verify pinout compatibility before substitution, as package variations do not affect logical function but impact physical mounting.
