What are the key features of CD74HC73E-NG?
- Dual independent JK flip-flops with negative-edge trigger enable versatile sequential logic in 2 V to 6 V designs
- 14-pin DIP (0.300" / 7.62 mm) package suits breadboard prototyping and through-hole PCB assembly
- High-speed CMOS technology provides low power consumption with TTL-compatible input thresholds for mixed-logic interfacing
What is CD74HC73E-NG used for?
CD74HC73E-NG serves as a building block for frequency dividers, shift registers, and state-machine circuits in hobbyist and industrial digital logic boards. Its dual JK structure suits toggle and set/reset flip-flop applications where two independent 1-bit storage elements are needed on a single IC. The device also fits legacy through-hole designs and educational platforms requiring reliable 2 V to 6 V CMOS sequential logic.

Frequently Asked Questions
What supply voltage range does CD74HC73E-NG support, and how does that affect logic level compatibility?
CD74HC73E-NG operates from 2 V to 6 V supply, covering both 3.3 V and 5 V system voltages. Its CMOS input thresholds scale with VCC, ensuring compatibility with TTL logic at 5 V and lower-voltage CMOS at 3.3 V in mixed-signal designs.
How does the negative-edge trigger of CD74HC73E-NG affect timing in a frequency-divider circuit?
Each JK flip-flop in CD74HC73E-NG clocks on the falling edge of the clock signal, dividing input frequency by 2 per stage. Chaining both elements produces a divide-by-4 counter, with propagation delay typically below 20 ns at 5 V supply for clock rates up to 25 MHz.
For a through-hole prototype, how does the 14-DIP package simplify breadboard assembly?
The 14-pin DIP with 0.300 inch row spacing and 7.62 mm pitch fits standard breadboards and DIP sockets directly, requiring no soldering for initial prototyping. This through-hole format accommodates both hand-soldering on single-sided PCBs and IC socket replacement without specialized tools.
When would CD74HC73E-NG be chosen over a surface-mount JK flip-flop like SN74HC73D?
CD74HC73E-NG is preferred in educational, prototyping, or service-replacement contexts where through-hole 14-DIP assembly is required and SMD rework is impractical. The -NG suffix indicates a non-green or legacy packaging variant, useful when replacing identical parts in existing boards running at 5 V with DIP IC sockets.
