DM74S175N

Overview

The DM74S175N is a high-speed Schottky logic integrated circuit manufactured by onsemi. It contains four positive-edge-triggered D-type flip-flops with independent data inputs and a common clear input. The device operates within a supply voltage range of 4.75V to 5.25V. It features a propagation delay of 9ns and supports clock frequencies up to 50MHz. The component utilizes bipolar technology and provides complementary outputs for each flip-flop.

Feature Summary

• Contains four independent positive-edge-triggered D-type flip-flops
• Features a single common clear input for all flip-flops
• Provides both non-inverting and inverting outputs per element
• Utilizes high-speed Schottky TTL circuitry

Applications

• High-speed digital data storage systems
• Parallel-to-serial conversion circuits
• Register file implementations in computing hardware
• Timing control logic in industrial automation

Procurement Notes

Verify the specific manufacturer prefix, as Texas Instruments produces the SN74S175 variant which shares identical logical functionality. Confirm that the DIP-16 package matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when high switching speed is required compared to standard or low-power logic families. The Schottky design offers faster performance than LS variants but consumes more power. Consider thermal management if multiple units are used in close proximity due to higher current draw inherent to the S series.

Part Context

This part belongs to the 74S (Schottky) family of logic devices, known for superior speed over standard 74 series components. It serves as a fundamental building block for sequential logic circuits requiring precise timing and data retention capabilities in high-performance digital applications.
