SN74S174NSR

Flip Flops Overview

The SN74S174NSR is a high-speed silicon-gate logic device from Texas Instruments, featuring six D-type flip-flops with clear inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 200 MHz. The component provides push-pull outputs with a propagation delay of 9 ns and output currents of -7.8 mA (high) and 7.8 mA (low). It is housed in a 16-pin SOIC package and 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 dedicated clear inputs for immediate state reset.
• Features Schmitt-trigger inputs to ensure noise immunity and clean signal transitions.
• Delivers high-speed performance with a maximum clock frequency of 200 MHz.

Flip Flops Applications

• High-speed digital data storage and register applications
• Parallel-to-serial conversion circuits
• Industrial control systems requiring wide temperature operation

Flip Flops Procurement Notes

Verify the specific suffix 'DR' against the requested 'SN74S174NSR', as datasheets indicate 'DR' corresponds to the SOIC-16 package variant. Confirm RoHS compliance status and check for automotive or military grade alternatives if extended reliability is required. Ensure the manufacturer source matches Texas Instruments specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when six synchronized D-type flip-flops are required for high-frequency logic operations. It is suitable for designs needing Schmitt-trigger input conditioning and robust performance across extreme temperatures. Consider the SOIC package constraints and verify that the 4.5V to 5.5V supply range aligns with the system power architecture.

Flip Flops Part Context

This device belongs to the SN74Sxx series of high-speed logic components. It serves as a hex version of the quadruple D-type flip-flop family, offering increased density compared to dual or quad variants while maintaining the fast switching characteristics typical of the S-series logic family.
