SN74S175D

Flip Flops Overview

The SN74S175D is a positive-edge-triggered D-type flip-flop from the Texas Instruments 74S series, housed in a 16-pin SOIC package. It contains four independent flip-flops with complementary outputs and a master reset function. Operating at a supply voltage of 4.75V to 5.25V, it features a maximum propagation delay of 12ns at 5V with 15pF load. The device supports a clock frequency up to 110 MHz, draws 96 mA static current, and provides output currents of 1mA (high) and 20mA (low).

Flip Flops Feature Summary

• Positive-edge triggering mechanism for precise data capture.
• Integrated master reset functionality for system initialization.
• Complementary outputs providing both true and inverted signals.

Flip Flops Applications

• High-speed digital data storage circuits.
• Parallel-to-serial conversion modules.
• State machine logic implementation.

Flip Flops Procurement Notes

Verify that the specific part number matches the requested 74S logic family specifications. Confirm the 16-SOIC package dimensions align with board layout requirements. Ensure the operating temperature range meets the application's thermal constraints. Cross-reference datasheet parameters against design needs before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when high switching speed is critical, as indicated by the 12ns delay and 110MHz clock capability. Consider the higher power consumption compared to LS or HC families. Ensure the 20mA low-level output current suffices for the driven loads without additional buffering.

Flip Flops Part Context

This device belongs to the Texas Instruments 74S (Schottky) logic family, known for superior speed performance over standard TTL. It serves as a quad D-type flip-flop solution within the broader 74xx series ecosystem, offering a balance between processing speed and interface compatibility for legacy and specialized digital systems.
