Note that the input pins are pulled down to ground through a 1k resistor, this way we can avoid the pin in floating condition.

Tl warrants performance of Its semiconductor products and related software to the specifications applicable at the time of sale In accordance with Tl’s standard warranty.

The clock signal here is just a push button but can be type of pulse like a PWM signal. Inclusion of Tl products In such applications Is understood to be fully at the risk of the customer.

Certain applications using semiconductor products may Involve potential risks of death, personal Injury, or severe property or environmental damage “Critical Datashee. The flip-flop will change its output only during the rising edge of the clock signal. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty. Arrow Electronics Mouser Electronics. Submitted by admin on 22 May Use of Tl products in such applications 74l107 the written approval of an appropriate Tl officer.

Load circuits and voltage waveforms are shown in Section 1.

IC Datasheet: 74LS107

Normally during regular operation of the IC the reset pin will be set high and the clock pulse of known frequency will be supplied to the clock pin, then the value o J and K will be varied based on the input signals and the respective output will be obtained on the Q and Q bar pins.


Products conform to specifications per the terms of Texas Instruments datsaheet warranty. The reset button should be pulled up through a 1K resistor and when grounded will reset the flip-flop. At the time of measurement, the clock input is grounded.

Meaning it has two JK flip flops inside it and each can be used individually based on our application. The term Datasgeet flip flop comes after its inventor Jack Kilby. It offers a large amount of data sheet, You can free PDF files download. Search the history of over billion web pages on the Internet. L e Low Logic Level.

Complete Technical Details can be found at the datasheet given at the end of this page. K data is processed by the flip-flops on the falling edge of.

Selling 74LS, 74LS, 74LSA with 74LS, 74LS, 74LSA Datasheet PDF of these parts.

This region of operation in highlighted in red colour on the Truth table above. Pin numbers shown are for D, J, and N packages. Clear and Complementary Outputs. Q 0 e The output logic level before the indicated input conditions were established. Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein.

The J-K input data is loaded into the master while the clock is high and transferred to the slave and the outputs on the high-to- low clock transistion.


TL — Programmable Reference Voltage. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. That is the pin will held to ground when the button is not pressed and when the button is pressed the pin will be held to supply voltage. The ‘LSA contain two independent negative-edge- triggered flip-flops.

This device contains two independent negative-edge-trig. Allied Electronics DigiKey Electronics. Full text of ” IC Datasheet: Questions concerning potential risk applications should be directed to Tl through a local SC sales office. The JK flip flop is considered to be more suitable for practical application because of its truth table that is the output of the flip flop will be stable for all types of inputs.

74LS107 Dual JK Flip-Flop with Clear

Toggle e Each output changes to the complement of its previous level on each falling edge of the clock pulse. Nor does Tl warrant or represent that any license, either express or implied.

The output state of the flip flops can be determined form the truth table below. H e High Logic Level. The J and K inputs must be stable prior to the high-to-low clock transition for predictable operation. For these devices the J and K inputs must be stable while the clock is high. Production processing does not 47ls107 include testing of all parameters. The updated every day, always provide the best quality and speed. L e Low Logic Level.
