Flip Flops datasheet and documents for SN74LS109AN

SN74LS109AN

Flip Flops Overview

The SN74LS109AN is a dual J-K positive-edge-triggered flip-flop from the Texas Instruments 74LS logic family. It integrates two independent circuits in a 16-pin PDIP package. The device operates within a supply voltage range of 4.75V to 5.25V, with a maximum propagation delay of 40ns at 5V and 15pF load. It features TTL-compatible inputs and outputs, providing a low-level output current of 8mA and a high-level output current of -400µA. The component supports preset and clear functions for direct control.

Flip Flops Feature Summary

Dual J-K positive-edge-triggered flip-flops with integrated preset and clear functionality
TTL-compatible input and output interfaces for standard logic integration
Low power Schottky (LS) technology ensuring reduced power consumption

Flip Flops Applications

General-purpose digital counting applications
Frequency division circuits
Shift register construction
Sequential logic control systems

Flip Flops Procurement Notes

Verify the specific suffix 'AN' corresponds to the plastic DIP-16 through-hole package variant. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure compatibility with 5V logic levels and check for any obsolete or discontinued status updates from Texas Instruments before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when dual J-K flip-flops with positive-edge triggering are required in a through-hole design. Consider the 40ns propagation delay and 8mA drive capability against system timing requirements. Evaluate the 74LS series characteristics regarding speed and power trade-offs compared to faster or lower-power alternatives if performance constraints exist.

Flip Flops Part Context

This part belongs to the SN74LS109 series, which includes variants such as SN74LS109ADG4 and SN74LS109ANE4. These components share the same logical function but differ in packaging options like SOIC or tape-and-reel formats. The SN74LS109AN specifically denotes the standard plastic DIP configuration suitable for prototyping and general PCB assembly.
