SN74HCS174DR

Flip Flops Overview

The SN74HCS174DR is a hex D-type flip-flop from Texas Instruments' HCS logic family, housed in a 16-pin SOIC package. It features Schmitt-trigger inputs and push-pull outputs with a reset function. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 200 MHz. Propagation delay is specified at 7 ns, with output currents of ±7.8 mA. It functions reliably across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Integrates six independent D-type flip-flops with positive-edge triggering and master reset functionality.
• Incorporates Schmitt-trigger inputs to ensure noise immunity and clean signal transitions.
• Delivers high-speed performance with a maximum clock frequency of 200 MHz and low propagation delay.

• Timing control and synchronization logic

Flip Flops Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with noise-tolerant inputs. The wide supply voltage range allows flexibility in power domains. Consider the SOIC package dimensions for PCB layout constraints and verify thermal management needs for operation at elevated temperatures within the specified industrial range.

Flip Flops Part Context

This device belongs to the SN74HCS series, which combines high-speed CMOS technology with Schmitt-trigger input stages. It offers improved noise margins compared to standard logic families while maintaining fast switching speeds. The HCS series is designed for demanding digital applications requiring reliable operation across varying environmental conditions and supply voltages.

Flip Flops Replacement Considerations

Direct pin-compatible alternatives within the same family include the SN74HCS174N (PDIP package) or other variants sharing the SN74HCS174 designation. Verify that any substitute maintains identical electrical characteristics, including propagation delay and output drive strength, to ensure circuit compatibility.
