SN74AHC174DBR

Flip Flops Overview

The SN74AHC174DBR is a hex D-type flip-flop with clear from the Texas Instruments AHC logic series. It features six independent circuits in an SOIC-Narrow-16 package. The device operates on a supply voltage range of 2 V to 5.5 V, with a propagation delay of 14.5 ns. Output drive capabilities include -8 mA high and 8 mA low currents. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops with asynchronous clear functionality
• Utilizes advanced AHC CMOS technology for high-speed operation
• Provides standard push-pull outputs compatible with CMOS logic families

Flip Flops Applications

• General-purpose digital data storage applications
• Shift register configurations for serial-to-parallel conversion
• State machine implementation in control systems

Flip Flops Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-16 package and reel packaging configuration. Confirm that the component meets RoHS compliance requirements for the target assembly process. Ensure the operating environment stays within the specified -40°C to +85°C temperature limits to maintain performance integrity.

Flip Flops Selection Notes

Select this component when six synchronized storage elements are required in a compact surface-mount footprint. The AHC series offers superior speed compared to standard HC logic while maintaining low power consumption. Verify input voltage levels match the system's logic family specifications for proper interfacing.

Flip Flops Part Context

This part belongs to the SN74AHC174 family of hex D-type flip-flops. It is functionally similar to other variants like the SN74AHC174DR but differs in package type. The DBR designation specifically indicates the narrow SOIC package suitable for space-constrained printed circuit board designs.

Flip Flops FAQ

What is the function of the clear pin?

The clear pin asynchronously resets all six flip-flops to a low state regardless of the clock or data inputs.

Is the output inverting or non-inverting?

The SN74AHC174DBR provides non-inverting outputs, meaning the Q output follows the D input state upon clock activation.
