SN74ALS109ANSR

Flip Flops Overview

The SN74ALS109ANSR is a dual positive-edge-triggered J-K flip-flop from Texas Instruments' Advanced Low-Power Schottky (ALS) logic family. It features TTL-compatible inputs and outputs, housed in an SOIC-14 surface-mount package. Key electrical parameters include a propagation delay of 18 ns, a low-level output current of 8 mA, and a high-level output current of -400 uA. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a minimum operating temperature of 0°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered J-K flip-flop configuration
• Advanced Low-Power Schottky (ALS) technology for optimized speed-power performance
• TTL-compatible input and output interfaces

Flip Flops Applications

• Digital counting circuits
• Frequency division networks
• Data storage elements in sequential logic systems

Flip Flops Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the SOIC-14 surface-mount package and reel packaging format. Confirm that the ALS series designation aligns with required power and speed specifications for the target application. Ensure compatibility with existing TTL logic levels and voltage supply constraints during integration.

Flip Flops Selection Notes

Select this component when dual J-K flip-flops are required with ALS speed characteristics. The SOIC-14 package suits surface-mount assembly processes. Consider the 18 ns propagation delay and 8 mA drive capability against system timing and load requirements. Verify availability of the specific reel quantity if mass production is planned.

Flip Flops Part Context

This part belongs to the SN74ALS109 family of dual J-K flip-flops. The 'A' indicates Advanced Low-Power Schottky technology, offering faster switching than standard LS series. The 'N' denotes the SOIC package type, while 'SR' specifies tape-and-reel packaging for automated placement.

Flip Flops Replacement Considerations

SN74ALS109AN (PDIP package), SN74F109DR (Faster F-series alternative), SN74LS109ADRE4 (Slower LS-series alternative). Verify pinout and electrical compatibility before substitution.
