SN74ALS374AN3

Flip Flops Overview

The SN74ALS374AN3 is an octal D-type edge-triggered flip-flop from Texas Instruments' Advanced Low-power Schottky (ALS) logic family. It features eight independent D-type flip-flops with three-state outputs, housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting. 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 functions with TTL input levels and non-inverting polarity across an operating 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

• Bus-oriented memory register implementations
• Clock-controlled data storage applications

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and functional equivalence. Ensure that the procurement channel provides valid traceability for the component. Confirm that the received units match the specified ALS series characteristics and packaging type before integration into designs requiring precise timing or voltage thresholds.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching with bus isolation capabilities. The ALS series offers a balance of speed and power efficiency suitable for general-purpose digital logic. Consider the 20-pin DIP package for prototyping or legacy board layouts. Verify that the required propagation delay and drive current meet the specific load conditions of the target application circuit.

Flip Flops Part Context

This part belongs to the SN74ALS374A series of octal D-type flip-flops. It is functionally similar to other octal registers but distinguished by its Advanced Low-power Schottky construction. The 'AN3' suffix typically denotes a specific manufacturing lot or tape-and-reel variant compared to standard tube packaging, though the core logical functionality remains consistent with the base SN74ALS374A specification.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS374 for standard LS logic requirements and the SN74HC374 for CMOS performance. Verify that alternative parts maintain the same 20-pin PDIP footprint and three-state output configuration to ensure mechanical and electrical compatibility without redesigning the host circuit.
