Frequently Asked Questions
What type of flip-flop is the CD74HC73EE4 and how many does it contain?
The CD74HC73EE4 contains two independent JK flip-flop elements (dual configuration), each with separate J, K, clock, and clear inputs, providing full flexibility for toggle, set, reset, and hold operations in sequential logic circuits.
What is the maximum clock frequency of the CD74HC73EE4?
The CD74HC73EE4 operates at a maximum clock frequency of 20MHz at nominal supply voltage, significantly faster than older CMOS 4000-series equivalents, enabling its use in higher-speed counter and divider circuits.
What package does the CD74HC73EE4 use?
The CD74HC73EE4 is packaged in a 14-pin DIP (Dual In-line Package) through-hole format, making it ideal for breadboard prototyping, educational electronics projects, and industrial PCB designs requiring through-hole soldering.
What is the output drive current of the CD74HC73EE4?
The CD74HC73EE4 provides a maximum output low current (I_OL) of 6mA, sufficient to directly drive TTL-compatible logic inputs and small LED indicators in typical 5V CMOS digital circuit applications.
What are common uses for the CD74HC73EE4?
Common applications include binary frequency division, ripple counters, synchronous state machines, clock edge detection circuits, shift register stages, and toggle latches in digital electronics projects, educational labs, and industrial logic board designs.
