SN74F175NSR

Flip Flops Overview

The SN74F175NSR is a quadruple D-type flip-flop from the Texas Instruments 74F series, housed in a 16-pin SOIC package. It features positive-edge triggering and includes an asynchronous clear input for each flip-flop. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 8 ns, a low-level output current of 20 mA, and a high-level output current of -1 mA. It supports a maximum clock frequency of 140 MHz and functions reliably within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains four independent D-type flip-flops with complementary outputs
• Positive-edge triggered by a common clock signal
• Includes individual asynchronous clear inputs for direct state reset

Flip Flops Applications

• High-speed digital data storage and buffering
• Shift register construction for serial-to-parallel conversion
• State machine implementation in logic circuits

Flip Flops Procurement Notes

Verify that the ordering suffix 'SR' corresponds to the tape-and-reel packaging format required for automated surface-mount assembly processes. Confirm that the specific variant matches the standard 74F series specifications without additional functional modifications indicated by the manufacturer's official documentation.

Flip Flops Selection Notes

Select this component when high switching speeds are critical, as the F series offers faster performance than standard TTL variants. Ensure the design accommodates the higher power consumption inherent to the F series compared to LS or ALS alternatives while maintaining compatibility with 5V logic levels.

Flip Flops Part Context

This part belongs to the Texas Instruments 74F (Fast) logic family, known for superior speed characteristics. It serves as a fundamental building block for sequential logic designs requiring rapid data capture and retention capabilities within standard integrated circuit architectures.

Flip Flops Replacement Considerations

Compatible substitutes include SN74F175N (through-hole DIP), SN74F175D (surface-mount SOIC), and SN74F175DR (reel-packaged SOIC). Cross-series replacements such as SN74ALS175 or SN74LS175 are possible but require verification of speed and power trade-offs.
