SN74ALS374AN

Flip Flops Overview

The SN74ALS374AN is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments within the ALS logic series. It features eight non-inverting D inputs and three-state outputs housed in a 20-pin PDIP package. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 16 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It supports through-hole mounting and functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains eight independent D-type edge-triggered flip-flops for parallel data storage
• Outputs provide three-state capability for bus-oriented systems
• Accepts TTL-compatible input signals directly

Flip Flops Applications

• Registering data in digital processing circuits
• Buffering memory addresses or data lines
• Implementing shift register configurations

Flip Flops Procurement Notes

Verify the specific ordering suffix 'AN' corresponds to the 20-pin PDIP package and standard commercial temperature range. Confirm RoHS compliance status as indicated in official documentation. Ensure the component matches the required logic family specifications for system compatibility before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring fast switching speeds with moderate power consumption. The ALS series offers superior performance compared to standard LS logic while maintaining lower power than AS logic. Verify that the 4.5 V to 5.5 V operating range aligns with the target circuit's power supply constraints.

Flip Flops Part Context

This part belongs to the SN74ALS374A family of octal flip-flops. It shares functional similarities with other variants like the SN74LS374N but provides faster switching characteristics due to the Advanced Low-power Schottky technology. The 'AN' suffix specifically denotes the plastic dual-in-line package configuration suitable for prototyping and general-purpose PCB layouts.

Flip Flops Replacement Considerations

The SN74ALS374ADWR serves as a surface-mount alternative offering identical logical functionality in a 20-SOIC package. Designers requiring leadless or smaller footprint solutions may consider this variant while maintaining pin-out compatibility.
