What are the key features of SN7472N?
- Master-slave J-K flip-flop architecture eliminates race conditions by latching inputs on the clock rising edge and updating outputs on the falling edge
- Three AND-ed J inputs and three AND-ed K inputs allow direct gating logic, reducing external gate count in sequential circuits
- Complementary Q and Q-bar outputs support both true and inverted signal paths for flexible counter and register designs
- Classic 14-pin DIP package compatible with breadboards and through-hole PCBs widely used in education and prototyping
What is SN7472N used for?
The SN7472N is used in digital logic design for frequency dividers, shift registers, and binary counters where a reliable clocked flip-flop with gated inputs is needed. Its master-slave operation makes it well-suited for synchronous sequential circuit design in educational laboratory settings and legacy industrial control boards. The part also appears in hobbyist and retro-computing projects that require standard TTL-compatible logic elements in a through-hole package.
