SN74ALS374ANS

Flip Flops Overview

The SN74ALS374ANS is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, belonging to the ALS logic series. It features a single element with eight bits per element and non-inverting outputs. The device utilizes a 20-pin SOIC package for surface mount installation. Key electrical parameters include a maximum propagation delay of 16 ns at 5V with 50pF load, a clock frequency of 35 MHz, and a supply voltage range of 4.5V to 5.5V. Output currents are specified as -2.6 mA for high level and 24 mA for low level, with a static current of 19 mA. The operating temperature range extends from 0°C to 70°C.

Flip Flops Feature Summary

• Octal D-type positive-edge triggered flip-flop configuration
• Three-state non-inverting outputs for bus-oriented systems
• ALS logic series performance with 16 ns propagation delay
• Surface-mount 20-SOIC package design

Flip Flops Applications

• Bus-oriented memory register applications
• High-speed timing circuits requiring edge triggering
• Data acquisition systems with three-state output control

Flip Flops Procurement Notes

Verify the specific suffix 'N' indicates a tube package variant distinct from the 'SR' reel version. Confirm RoHS compliance status and MSL rating prior to ordering. Ensure the supplier provides official datasheets matching the exact part number to avoid confusion with similar ALS family components. Cross-reference pinouts and electrical characteristics against the manufacturer's latest documentation.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for bus-driven architectures. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Consider the 20-SOIC package constraints for PCB layout. Verify that the 4.5V to 5.5V supply range aligns with the system voltage requirements and that the 35 MHz clock frequency meets the application timing needs.

Flip Flops Part Context

This part belongs to the SN74ALS374 family of octal D-type flip-flops. It is functionally equivalent to other variants like SN74ALS374ADW or SN74ALS374ANSR, differing primarily in packaging and shipping format. The ALS series represents an advanced low-power Schottky technology, providing faster switching speeds than standard TTL while maintaining lower power dissipation. It serves as a foundational component for sequential logic design in mixed-signal environments.
