SN74AC174PWRQ1

Flip Flops Overview

The SN74AC174PWRQ1 is an automotive-grade, six-channel D-type flip-flop manufactured by Texas Instruments. It features a shared active-low clear (CLR) input and positive-edge-triggered clock (CLK) inputs. The device operates within a supply voltage range of 1.5 V to 6 V and supports continuous output drive currents of ±24 mA at 5 V, with short-pulse support up to ±75 mA. It is housed in a TSSOP-14 package and complies with AEC-Q100 standards for Grade 1, ensuring operation across a temperature range of -40°C to +125°C.

Flip Flops Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and tape/reel specifications. Ensure the component meets the required AEC-Q100 reliability standards for the target automotive application. Confirm that the operating temperature range aligns with the system's thermal environment requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with a common reset function. The wide voltage range allows compatibility with both low-power and standard logic interfaces. Consider the TSSOP-14 footprint for PCB layout constraints and verify that the propagation delay characteristics meet the timing requirements of the synchronous design.

Flip Flops Part Context

This part belongs to the SN74AC174-Q1 family of automotive logic devices. It provides a robust solution for high-reliability digital systems where space efficiency and broad voltage tolerance are critical. The integration of six channels into a single package reduces board area compared to discrete solutions.

Flip Flops Replacement Considerations

Direct substitutes include other SN74AC174-Q1 variants with different packaging options such as SN74AC174PW or SN74AC174DBVR. Verify that any replacement maintains the same AEC-Q100 grade and electrical characteristics.
