SN74LS374N

Flip Flops Overview

The SN74LS374N is an octal D-type flip-flop manufactured by Texas Instruments, not onsemi. It features edge-triggered data storage with three-state outputs for bus-oriented systems. The device operates within a supply voltage range of 4.75V to 5.25V and supports through-hole mounting in a 20-PDIP package. Key electrical parameters include a propagation delay of 28ns at 5V, high-level output current of -2.6mA, and low-level output current of 24mA. It functions as a transparent latch or edge-triggered flip-flop suitable for buffering and I/O ports.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight independent edge-triggered storage elements
• Three-state outputs enable direct connection to system buses without additional interface logic
• Non-inverting polarity ensures logical consistency between input data and stored output states

Flip Flops Applications

• Buffer registers for temporary data storage in digital systems
• I/O port interfaces connecting microprocessors to peripheral devices
• Bidirectional bus drivers managing data flow across shared communication lines

Flip Flops Procurement Notes

Verify manufacturer origin carefully, as the SN74LS374N is primarily produced by Texas Instruments. Confirm that any onsemi-supplied units are cross-compatible equivalents rather than original TI components. Check datasheet specifications against required voltage and current parameters to ensure functional equivalence in existing designs.

Flip Flops Selection Notes

Select this component when designing TTL-compatible circuits requiring octal storage with bus isolation. Ensure the application environment stays within the specified 0°C to 70°C operating temperature range. Verify that the 5V logic level matches the system's power supply and signal integrity requirements before integration.

Flip Flops Part Context

This component belongs to the standard 74LS series of logic integrated circuits, widely used in legacy and industrial digital electronics. The SN74LS374N specifically addresses the need for multi-bit storage with tri-state control, forming a fundamental building block for memory interfaces and data routing in parallel architectures.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74LS374DW and DM74LS374N. Cross-reference pinouts and electrical characteristics to ensure compatibility during design updates or supply chain adjustments.
