SN74ALS109ADR

Flip Flops Overview

The SN74ALS109ADR is a dual J-K positive-edge-triggered flip-flop from Texas Instruments' ALS logic series, housed in a 16-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input/output levels. 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 functions reliably across an operating temperature range starting from 0°C.

Flip Flops Feature Summary

• Dual J-K flip-flops with positive-edge triggering
• Includes preset and clear control inputs
• Compatible with TTL input and output levels

Flip Flops Applications

• Digital data storage circuits
• Frequency division networks
• Shift register implementations

Flip Flops Procurement Notes

Verify the specific suffix 'ADR' corresponds to the SOIC-16 surface-mount package variant when sourcing. Confirm that the ALS logic family specifications align with system power and speed requirements. Ensure compatibility with existing PCB footprints designed for this package type before finalizing procurement orders.

Flip Flops Selection Notes

Select this component for applications requiring moderate speed and standard drive capability within the ALS family. The SOIC-16 package facilitates automated surface-mount assembly. Consider the 18 ns propagation delay and 8 mA sink current against circuit timing and load constraints during design integration.

Flip Flops Part Context

This part belongs to the SN74ALS109A series of dual J-K flip-flops. It shares functional characteristics with other devices in the ALS logic family, offering improved performance over standard LS logic while maintaining pinout compatibility with legacy designs. The ADR suffix specifically denotes the tape-and-reel packaging format for the SOIC-16 variant.
