So if you are looking for a IC for latching purpose or to 74lw107 as a small programmable memory for you project then this IC might be the right choice for you. TL — Programmable Reference Voltage. Pin numbers shown are for D, J, and N packages.

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.

IC Datasheet: 74LS107

Arrow Electronics Mouser Electronics. June DM54LSA DM74LSA Dual Negative-Edge- Triggered Master-Slave J-K Flip-Flops with Clear and Complementary Outputs General Description This device contains two independent negative-edge-trig- gered J-K flip-flops with complementary outputs The J and K data is processed by the flip-flops on the falling edge of the clock pulse The clock triggering occurs at a voltage level and is not directly related to the transition time of the negative going edge of the clock pulse The data on the J and K inputs may change while the clock is high or low without affecting the outputs as long as setup and hold times are not violated A low logic level on the clear input will reset the outputs regardless of the logic levels of the other inputs Connection Diagram www.

Certain applications using semiconductor products may Involve potential risks of death, personal Injury, or severe property or environmental damage “Critical Applications”. Products conform to specifications per the terms of Texas Instruments standard warranty. Meaning it has two JK flip flops inside it and each can be used individually based on our application.


The JK flip flops are considered dahasheet be the most efficient flip-flop and can be used for certain applications on its own. This device contains two independent negative-edge-trig. Submitted by admin on 22 May Q 0 e The output logic level before the indicated input conditions were established. The clock signal here is just a push button but can be type of pulse like a PWM signal.

L e Low Logic Level. This device contains two independent negative-edge-trig.

Tl assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Use of Tl products in such applications requires the written approval of an appropriate Tl officer. At the time datahseet measurement, the clock input is datssheet.

The below circuit shows a typical sample connection for the JK flip-flop. For these devices the J and K inputs must be stable while the clock is high. K data is processed by the flip-flops on the falling edge of.

This region of operation in highlighted in red colour on the Truth table above. Is granted under any patent right, copyright, mask work right, or other intellectual property right of Tl covering or relating to any combination, machine, or process in which such semiconductor products or services might be or are used.

Production processing does not necessarily include testing of all parameters.

Nor does Tl warrant or represent that any license, either express or implied. Physical Dimensions inches millimeters Continued.

Allied Electronics DigiKey Electronics. Complete Technical Details can be found at the datasheet given at the end of this page. The JK flip flop is considered to be more suitable dataeheet practical application because of its truth table that is the output of the flip flop will be stable for all types of inputs.


The output state of the flip flops can be determined form the truth table below. The flip-flops are also called as latching devices meaning it can remember one single bit of data and latch the output based on it, due to this property they are commonly used as shift registers, control registers, storage registers or where ever a small memory is required. H e High Logic Level. The term JK flip flop comes after its inventor Jack Kilby. 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 dayasheet supply voltage.

The dtaasheet circuit shows a typical sample connection for the JK flip-flop The J and K pins are the input pins for the Flip-Flop and the Q and Q bar pins are the output pins.

Q 0 e The output logic level before the indicated input conditions were established.

Load circuits and voltage waveforms are shown in Section 1. In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards should be provided by the customer to minimize Inherent or procedural hazards. Clear and Complementary Outputs. The reset button should be pulled up through a 1K resistor and 74os107 grounded will reset the flip-flop.
