DM74S374N

Overview

The DM74S374N is an octal D-type flip-flop manufactured by onsemi, belonging to the 74S logic series. It features eight edge-triggered D-type flip-flops with three-state outputs in a single package. The device operates within a supply voltage range of 4.75V to 5.25V and exhibits a maximum propagation delay of 12ns at 5V. It provides high-level output current of 6.5mA and low-level output current of 20mA. The component is housed in a 20-PDIP (0.300", 7.62mm) package and supports through-hole mounting.

Feature Summary

• Octal configuration containing eight independent edge-triggered D-type flip-flops for parallel data storage.
• Three-state outputs allow direct connection to bus systems without additional interface components.
• High-speed switching characteristics typical of the 74S logic family for rapid signal processing.

Applications

• Buffer registers for temporary data storage in digital circuits
• I/O port interfaces for connecting peripheral devices
• Bidirectional bus drivers for managing data flow across system lines

Procurement Notes

Verify component authenticity carefully as this part number is discontinued. Check datasheets for exact pinout compatibility with legacy designs. Confirm that replacement alternatives meet the required 74S series electrical specifications and package dimensions. Ensure sourcing channels provide valid documentation for quality assurance purposes before integration into production.

Selection Notes

Select this component when designing systems requiring octal storage with high-speed performance. Consider the 74S series speed-power trade-offs compared to other logic families. Verify that the three-state output capability aligns with the target bus architecture requirements. Ensure the operating temperature range meets the environmental conditions of the intended application scenario.

Part Context

This device belongs to the standard 74-series logic family, specifically the Schottky (S) variant known for improved speed. It serves as a fundamental building block for sequential logic circuits. The octal format allows handling multiple bits simultaneously, reducing component count in complex digital designs compared to single-bit flip-flop solutions.
