SN74ALS74AN

Flip Flops Overview

The SN74ALS74AN is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments ALS logic series. It features TTL-compatible inputs and outputs, housed in a 14-pin PDIP package for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to +70°C. Key electrical specifications include a propagation delay of 18 ns, a low-level output current of 8 mA, and a high-level output current of -400 uA.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flop architecture
• TTL-compatible input and output levels
• Inverting and non-inverting output polarities

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel configuration, as variations exist within the SN74ALS74A family. Ensure that the procurement documentation explicitly references the SN74ALS74AN part number to distinguish it from other variants with different pin counts or electrical characteristics. Cross-reference the manufacturer's official datasheet for the most current mechanical dimensions and thermal requirements before finalizing component selection.

Flip Flops Selection Notes

Select this component when designing systems requiring dual D-type storage elements with TTL compatibility and through-hole packaging constraints. The ALS series offers improved speed and power consumption compared to standard LS logic. Consider the 18 ns propagation delay and 8 mA sink capability when driving subsequent loads. Verify that the application environment remains within the specified 0°C to +70°C temperature range for reliable operation.

Flip Flops Part Context

This component belongs to the SN74ALS74A series, which represents the Advanced Low-power Schottky logic family produced by Texas Instruments. The ALS family provides a balance between power efficiency and switching speed, making it suitable for general-purpose digital logic applications. The 'AN' suffix specifically denotes the plastic dual in-line package variant designed for through-hole PCB assembly methods.
