SN74S175NSR

Flip Flops Overview

The SN74S175NSR is a quadruple D-type flip-flop with clear, belonging to the Texas Instruments S series of logic devices. It features TTL-compatible inputs and outputs, operating within a supply voltage range of 4.75 V to 5.25 V. The component utilizes a 16-pin Small Outline Package (SOIC) for surface-mount installation. Key electrical characteristics include a propagation delay of 17 ns, a high-level output current of -1 mA, and a low-level output current of 20 mA. It supports an operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Integrates four independent D-type flip-flops with complementary outputs in a single package
• Features positive edge triggering for precise data synchronization
• Includes a dedicated clear input for immediate asynchronous reset functionality
• Provides TTL-compatible interface levels for direct connection to standard logic systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications
• Timing and control logic systems

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the device variant matches the required industrial or commercial temperature rating. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a quadruple D-type flip-flop with a clear function is required in a surface-mount design. The S series offers faster switching speeds compared to standard LS logic families. Verify that the system operates within the specified 4.75 V to 5.25 V supply voltage range and that the 17 ns propagation delay meets the timing requirements of the application.

Flip Flops Part Context

This device is part of the SN74Sxx family of Schottky TTL logic components. The SN74S175 specifically provides four D-type flip-flops with clear, distinguishing it from variants like the SN74S374 which lack the clear input. It serves as a fundamental building block for sequential logic circuits requiring compact surface-mount integration.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include the SN74S175N in a PDIP package, though physical mounting differs. Other S-series quad D-type flip-flops with clear may be considered if package constraints allow.
