The JK flip-flop is a logic circuit element that can be used to store and manipulate binary data. In the field of digital electronics, JK triggers are usually composed of multiple logic gates rather than a single chip.
JK flip-flops can be implemented by a variety of logic gates, such as using logic gates in integrated circuit (IC) chips, such as AND gates, OR gates, and NOT gates. Common integrated circuit families, such as the 74 series and 4000 series, offer a variety of logic gate chips that can be used to build JK triggers.
Specifically, the JK flip-flop can be composed of multiple logic gate chips (such as 74LS73, 74LS109, etc.), which contain logic gate circuits to achieve the function of the JK flip-flop.
It should be noted that the JK trigger is not the name of a single chip, but the name of a logic circuit, which can be composed of multiple chips.

The TTL 74LS73 is a dual JK flip-flop IC, which contains two separate JK typed bistable in a single chip and can make a single or master-slave trigger
