SN74ALS74ANS

Flip Flops Overview

The SN74ALS74ANS is a dual positive-edge-triggered D-type flip-flop from Texas Instruments' Advanced Low-power Schottky (ALS) logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs and outputs. The device provides both non-inverting (Q) and inverting (/Q) outputs for each flip-flop. Key electrical specifications include a propagation delay of 18 ns, a low-level output current capability of 8 mA, and a high-level output current of -400 uA. It is housed in a 14-pin SOIC package.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with positive-edge triggering
• Advanced Low-power Schottky technology for high-speed operation
• TTL-compatible input and output levels
• Provides complementary Q and /Q outputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Digital state storage and memory elements
• Timing and synchronization logic

Flip Flops Procurement Notes

Verify the specific suffix 'AN' confirms the SOIC-14 surface-mount package variant. Confirm RoHS compliance status via the official datasheet as requirements vary by manufacturing date code. Ensure the ALS series availability aligns with current production cycles, as legacy logic families may have limited stock or obsolescence risks compared to modern alternatives.

Flip Flops Selection Notes

Select this component when designing systems requiring moderate speed with low power consumption using the ALS standard. It is suitable for applications needing two independent storage elements in a compact surface-mount footprint. Consider the 18 ns propagation delay against system clock speeds. Verify that the 4.5 V to 5.5 V operating range matches the target power supply infrastructure.

Flip Flops Part Context

This part belongs to the SN74ALS74A series, which contains dual D-type flip-flops. The 'ALS' designation indicates Advanced Low-power Schottky logic, offering a balance between speed and power dissipation superior to standard LS logic. The 'SN' prefix typically denotes commercial temperature range devices manufactured by Texas Instruments.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include the SN74LS74AN for standard LS logic performance. For equivalent ALS performance, verify availability of other manufacturers' ALS74 equivalents. Ensure replacement parts maintain the same SOIC-14 package and voltage specifications.
