Flip Flops datasheet and documents for SN74LS109ANS

SN74LS109ANS

Flip Flops Overview

The SN74LS109ANS is a dual J-K positive-edge-triggered flip-flop manufactured by Texas Instruments in the LS logic series. It features two independent circuits within a 16-pin PDIP package. The device operates with a supply voltage range of 4.75 V to 5.25 V and includes preset and clear inputs for direct control. Key electrical parameters include a propagation delay of 40 ns, a high-level output current of -400 µA, and a low-level output current of 8 mA. It supports TTL input and output types with inverting/non-inverting polarity options.

Flip Flops Feature Summary

Dual J-K positive-edge-triggered flip-flops with integrated preset and clear functions
Compatible with standard TTL input and output logic levels
Low power Schottky (LS) technology for reduced power consumption

Flip Flops Applications

Digital counters and frequency dividers
Shift registers for data storage and transfer
State machines and sequential logic circuits

Flip Flops Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official documentation to confirm pinout, package dimensions, and electrical characteristics match the required design specifications. Ensure that the lead time and availability status are confirmed directly with authorized distributors or the manufacturer prior to ordering, as these factors may vary based on production schedules and regional distribution channels.

Flip Flops Selection Notes

Select this component when designing circuits requiring dual J-K flip-flops with positive-edge triggering and asynchronous preset/clear capabilities. The LS series offers a balance of speed and power efficiency suitable for general-purpose digital logic applications. Consider the 16-pin DIP package for through-hole prototyping or legacy board designs requiring compatible footprints.

Flip Flops Part Context

This part belongs to the Texas Instruments 74LS109 family of dual J-K flip-flops. It is part of the broader 74xx series of logic ICs, widely used in digital electronics for memory elements and sequential control. The LS variant specifically denotes Low-power Schottky technology, providing improved performance over standard TTL while maintaining compatibility.
