SN74AC174WBQBRQ1

Flip Flops Overview

The SN74AC174WBQBRQ1 is an automotive-grade hex D-type flip-flop from Texas Instruments, compliant with AEC-Q100 standards. It features six independent D-type triggers with a shared active-low clear (CLR) and positive-edge-triggered clock (CLK) input. The device operates within a supply voltage range of 1.5 V to 6 V and supports a maximum clock frequency of 150 MHz. It utilizes a WQFN-16 package and provides push-pull outputs capable of ±24 mA drive current. The component functions across an extended temperature range of -40°C to +125°C.

Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package variant and quality grade. Confirm that the WQFN-16 footprint aligns with the target PCB layout constraints. Ensure the selected part number corresponds to the correct tape-and-reel quantity specifications for the manufacturing process. Cross-reference the datasheet revision date to guarantee compatibility with current design requirements.

Flip Flops Selection Notes

Select this component when designing automotive systems requiring high-density hex D-type logic with wide voltage tolerance. The AC series offers faster propagation delays compared to standard variants, suitable for higher-speed synchronous designs. Consider the WQFN-16 package for space-constrained layouts while maintaining robust thermal and mechanical performance in harsh environments.

Flip Flops Part Context

This part belongs to the SN74AC174-Q1 family of automotive hex D-type flip-flops. It shares functional characteristics with other members of the SN74ACT and SN74AC series but is specifically optimized for automotive reliability. The WBQB suffix indicates the WQFN-16 package configuration, distinguishing it from other pinout or package options within the same logical family.

Flip Flops FAQ

How does the clock triggering mechanism function in this device?

Clock triggering occurs at specific voltage levels and is not directly related to the transition time of the CLK positive edge. Data on the D input must meet setup time requirements before the rising edge to be transferred to the output.

What is the impact of the CLR input state on the outputs?

The clear (CLR) input is active-low. When asserted low, it resets all six flip-flops regardless of the clock or data input states. When high, normal operation based on the clock edge proceeds.
