SN74HC174D

Flip Flops Overview

The SN74HC174D is a hex D-type flip-flop from the Texas Instruments 74HC series, housed in a 16-pin SOIC package. It features Schmitt-trigger inputs for noise immunity and push-pull outputs capable of driving up to 7.8 mA. The device operates on a supply voltage range of 2 V to 6 V with a maximum clock frequency of 50 MHz. Propagation delay is typically 160 ns at 2 V and 30 ns at 6 V. It includes a master reset function and supports an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Hex D-type flip-flops with Schmitt-trigger inputs
• Push-pull outputs with high drive capability
• Master reset functionality

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Timing control circuits

Flip Flops Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required package style and temperature grade before procurement.

Flip Flops Selection Notes

Select this component when six independent D-type flip-flops are required in a single package. The HC series offers CMOS compatibility and low power consumption. Verify that the 50 MHz maximum clock frequency meets system timing requirements and that the SOIC-16 package fits the PCB layout constraints.

Flip Flops Part Context

This component belongs to the standard 74HC logic family, providing high-speed CMOS performance. It is part of a broader catalog of hex flip-flops including variants like the SN74HCS174 and automotive-grade SN74HC174QPWRQ1. The SN74HC174D specifically denotes the industrial temperature range and SOIC packaging.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74HC174PWR (TSSOP-16) and SN74HC174N (DIP-16). Cross-reference pinouts and electrical characteristics to ensure functional equivalence.
