DM74175N

Overview

The DM74175N is a quad D-type flip-flop utilizing standard TTL circuitry. It features positive-edge triggering with direct clear inputs and complementary outputs for each stage. The device operates on a 5 V supply, drawing a maximum current of 20 mA. It supports a typical clock frequency of 40 MHz and has a propagation delay of 35 ns. Packaged in a 16-pin DIP, it functions as asynchronous storage elements within digital logic systems.

Feature Summary

• Positive-edge-triggered D-type flip-flop architecture
• Complementary Q and /Q outputs per channel
• Direct clear input for immediate state reset
• Buffered clock and data inputs

Applications

• Buffer and storage registers
• Shift registers
• Pattern generators

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor is now part of Texas Instruments. Ensure the specific suffix matches the required package type and temperature range. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference datasheet revisions to ensure pinout and electrical characteristics remain consistent with your design requirements.

Selection Notes

Select this component when designing synchronous circuits requiring four independent D-type storage elements with clear functionality. It is suitable for standard TTL logic families where 5 V operation is standard. Consider the 35 ns propagation delay and 40 MHz clock limit for timing analysis. Ensure adequate power dissipation handling for the specified load conditions.

Part Context

This component belongs to the 74 series of logic integrated circuits, specifically the D-type flip-flop category. It is manufactured by National Semiconductor, which was acquired by Texas Instruments. The device represents a standard solution for basic sequential logic operations in legacy and compatible digital designs.

Replacement Considerations

The DM74LS175N from Fairchild or Texas Instruments offers equivalent logical functionality. Verify that the replacement maintains the same 16-pin DIP package and TTL voltage levels. Check for any differences in propagation delay or power consumption that might affect system timing.
