SN74LS175NSR

Flip Flops Overview

The SN74LS175NSR is a quadruple D-type flip-flop from the Texas Instruments LS logic family, housed in an 8-pin SOIC surface-mount package. It operates on a supply voltage of 4.75V to 5.25V and features four independent D-type circuits with positive-edge triggering. The device provides both true and complement outputs for each flip-flop, includes a master clear input, and supports a maximum clock frequency of 40 MHz with a typical propagation delay of 25 ns.

Flip Flops Feature Summary

• Quadruple D-type architecture with positive-edge triggering
• Simultaneous true and complement output availability
• Master clear function for synchronous initialization
• Surface-mount packaging for automated assembly

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Frequency division circuits
• Digital timing control systems

Flip Flops Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the specific tape-and-reel packaging variant required for your surface-mount production line. Confirm that the SOIC-8 footprint matches your PCB design constraints. Ensure the LS logic family compatibility aligns with existing TTL interface requirements in the target system design.

Flip Flops Selection Notes

Select this component when a compact surface-mount solution for quadruple D-type storage is required. The LS series offers a balance of speed and power consumption suitable for general-purpose digital logic applications. Consider the 8-pin package density if board space is limited compared to larger DIP alternatives.

Flip Flops Part Context

This part belongs to the standard 74LS series of digital logic integrated circuits manufactured by Texas Instruments. The SN74LS175 specifically implements four independent D-type flip-flops within a single chip, providing a cost-effective solution for multi-bit data storage and transfer operations in digital electronics.

Flip Flops Replacement Considerations

Compatible substitutes include SN74LS175N (DIP version) and SN74LS175DE4 (SOIC version). Verify pinout compatibility and electrical specifications before substitution.
