SN74HC174DR

Flip Flops Overview

The SN74HC174DR is a hex D-type flip-flop from Texas Instruments' HC logic family. It features six independent positive-edge-triggered D-type flip-flops with a common master reset input. The device operates within a supply voltage range of 2 V to 6 V and utilizes a 16-pin SOIC package for surface-mount installation. Key electrical specifications include a maximum propagation delay of 160 ns at 2 V and output drive currents of ±5.2 mA. The component supports an operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops with positive-edge triggering
• Includes a common master reset input for synchronous clearing
• Features Schmitt-trigger inputs on clock lines for noise filtering

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• General-purpose storage elements in digital systems

Flip Flops Procurement Notes

Verify the specific datasheet revision and package marking code upon receipt to ensure compliance with the SN74HC174DR specification. Confirm that the device meets RoHS requirements if mandated by the project standards. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and functional parameters before integration into production designs.

Flip Flops Selection Notes

Select this component when a high-density hex D-type flip-flop solution is required within standard CMOS logic families. The HC series offers balanced speed and power consumption suitable for general-purpose applications. Ensure the design accommodates the specified 2 V to 6 V supply range and verify that the 160 ns propagation delay aligns with the system timing constraints.

Flip Flops Part Context

This part belongs to the SN74HC174 series, which provides hex D-type flip-flops. It is distinct from other variants like the SN74HCS174 (Schmitt-trigger inputs) or SN74AHC174 (advanced high-speed CMOS). The 'D' suffix indicates the SOIC package type, differentiating it from TSSOP or other form factors available within the same logical function family.
