74107 Dual JK Flip-Flop IC DIP-14

Description

74107 Dual JK
Flip-Flop IC
DIP-14 – Reliable Digital Memory

The 74HC107 is a JK Flip-Flop with individual J, K, Direct Clear, and Clock Pulse inputs. Output changes are initiated by the HIGH-to-LOW transition of the clock. The J and K inputs must be stable one setup time prior to the high-to-low clock transition for predictable operation. The 74HC107 IC has a wide range of working voltage, and a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL.

What is a JK Flip-Flop?

The JK Flip Flop is basically a gated RS flip flop with the addition of the clock input circuitry. When both the inputs S and R are equal to logic “1”, the invalid condition takes place. Thus to prevent this invalid condition, a clock circuit is introduced. The JK Flip Flop has four possible input combinations because of the addition of the clocked input. The four inputs are “logic 1”, ‘logic 0”. “No change’ and “Toggle”.

Features:
