DM74LS534N

Overview

The DM74LS534N is an octal D-type flip-flop with three-state outputs manufactured by onsemi. It operates within a supply voltage range of 4.75V to 5.25V and supports through-hole mounting in a 20-pin DIP package. The device features output current capabilities of 2.6mA for high state and 24mA for low state, ensuring robust signal driving. Designed for commercial temperature ranges from 0°C to 70°C, it provides reliable digital storage and buffering functionality for standard logic applications requiring precise timing control.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements
• Three-state outputs enabling direct bus line connections without external buffers
• High noise immunity characteristics inherent to the LS logic family design

Applications

• Digital data storage and register circuits
• Bus-oriented memory systems
• Parallel-to-serial data conversion modules

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with 5V logic levels and check pinout alignment for existing PCB footprints. Confirm that the manufacturer source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when an octal storage solution with tri-state capability is required for 5V logic systems. Consider the 20-pin DIP package for prototyping or through-hole manufacturing needs. Evaluate the 24mA low-state sink current against load requirements to ensure adequate drive strength for connected circuitry.

Part Context

This part belongs to the industry-standard 74LS series of logic devices, widely utilized for general-purpose digital logic functions. As an octal flip-flop, it serves as a fundamental building block for sequential logic circuits, offering a balance of speed and power consumption typical of Low-power Schottky technology.

Replacement Considerations

Cross-reference with other manufacturers' 74LS534 equivalents such as SN74LS534 or MC14534B variants. Verify electrical parameter compatibility, particularly output current ratings and supply voltage tolerances, before substituting to maintain system integrity.
