SN74AS74ANSR

Flip Flops Overview

The SN74AS74ANSR is a dual D-type flip-flop from the Texas Instruments AS logic series, housed in a 14-pin SOIC package. It features dual positive-edge triggering with both inverting and non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical parameters include a propagation delay of 9 ns, a low-level output current of 20 mA, and a high-level output current of -2 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual positive-edge triggered D-type flip-flops integrated into a single package
• Provides both inverting and non-inverting output configurations for flexible logic interfacing
• Compatible with standard TTL input and output voltage levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Flip Flops Procurement Notes

Verify that the specific part number matches the required AS logic family specifications, as performance characteristics differ significantly from other 74-series variants. Confirm the SOIC-14 package type aligns with PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the target application. Cross-reference official datasheets for precise timing and electrical limits before finalizing component selection.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage with mixed polarity outputs is required within the AS logic family constraints. Consider the 9 ns propagation delay and specific drive currents against system timing budgets. Evaluate the 4.5 V to 5.5 V supply requirement to ensure compatibility with existing power rails. Compare against alternative families if lower power consumption or wider voltage ranges are necessary for the design.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74AS74A series, representing the Advanced Schottky (AS) logic family. This family offers higher speed performance compared to standard 74-series logic while maintaining TTL compatibility. The SN74AS74ANSR variant specifically denotes the surface-mount SOIC-14 package configuration, designed for automated assembly processes in compact electronic designs.

Flip Flops Replacement Considerations

Direct functional substitutes within the same manufacturer's portfolio may include other dual D-type flip-flops from the AS series, such as the SN74AS74AN. Verify pinout compatibility and electrical specifications when considering cross-family replacements like those from the ALS or ABT series.
