DM74S175N

Overview

The DM74S175N is a Schottky TTL quad D-type flip-flop featuring positive-edge triggering and direct clear inputs. It provides complementary Q and /Q outputs for each of the four flip-flops. The device operates with a supply voltage range of 4.75V to 5.25V, supporting a typical clock frequency of 40 MHz. Propagation delay is typically 8 ns, with power dissipation per flip-flop at approximately 30 mW. Packaged in a 16-pin DIP.

Feature Summary

• Positive-edge-triggered D-type logic implementation
• Complementary output pairs for each flip-flop
• Direct asynchronous clear input functionality

Applications

• Buffer and storage registers
• Shift register configurations
• Pattern generators

Procurement Notes

Verify the manufacturer designation prefix (DM) aligns with Fairchild Semiconductor specifications rather than Texas Instruments or National Semiconductor variants. Confirm the 'N' suffix corresponds to the standard plastic dual-in-line package. Ensure the component meets Schottky TTL electrical characteristics distinct from LS series counterparts.

Selection Notes

Select this component when high-speed switching performance is required compared to standard LS logic families. The Schottky process offers improved propagation delays suitable for memory decoding and data transmission systems. Verify that the 16-pin DIP form factor fits the target PCB layout constraints.

Part Context

This part belongs to the DM74Sxx Schottky TTL family, designed for high-performance applications requiring low propagation delay. It serves as a faster alternative to the DM74LS175N while maintaining functional compatibility. The S-series utilizes ion-implanted Schottky diodes to minimize switching times.

Replacement Considerations
