Key Features
- 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
Applications
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.

Frequently Asked Questions
What type of flip-flop is the SN7472N?
The SN7472N is a master-slave J-K flip-flop, which captures the J and K input states on the rising edge of the clock and transfers them to the output on the falling edge, preventing output glitches during the clock high phase.
How many J and K inputs does the SN7472N have?
The SN7472N has three AND-ed J inputs and three AND-ed K inputs. All three J inputs must be high to assert J, and all three K inputs must be high to assert K, providing built-in gating functionality without extra logic gates.
What package does the SN7472N come in?
The SN7472N comes in a 14-pin plastic dual in-line package (DIP-14), a through-hole format that is easy to insert into breadboards or standard IC sockets for prototyping and repair of legacy boards.
What logic family does the SN7472N belong to?
The SN7472N is part of the classic TTL (Transistor-Transistor Logic) family, which operates at 5 V and is compatible with the broad ecosystem of 74-series logic devices used in digital design for decades.
What are typical applications for the SN7472N?
Typical applications include binary counters, frequency dividers, shift register stages, and sequential state machines in educational electronics labs, legacy industrial controllers, and hobbyist digital circuit projects.
