Frequently Asked Questions
What type of flip-flop is the CD74AC74E-NG?
The CD74AC74E-NG is a dual D-type positive-edge-triggered flip-flop, meaning data is captured on the rising edge of the clock signal. It contains 2 independent flip-flop elements, each storing 1 bit of data with individual set and reset inputs.
What package does the CD74AC74E-NG use?
The CD74AC74E-NG comes in a 14-DIP (Dual-In-Line Package) with a 0.300 inch (7.62 mm) row spacing. This through-hole package is ideal for breadboard prototyping, hand soldering, and applications requiring easy component replacement.
What logic family does the CD74AC74E-NG belong to?
The CD74AC74E-NG belongs to the Advanced CMOS (AC) logic family, which offers high-speed operation comparable to TTL logic while maintaining the low power consumption characteristic of CMOS technology, making it suitable for battery-powered and high-frequency designs.
What are typical applications for the CD74AC74E-NG?
Common applications include data registers, frequency dividers (divides clock by 2), pipeline stages, synchronous state machines, and clock domain crossing buffers. The dual configuration allows two independent 1-bit storage elements in a single 14-pin IC.
Is the CD74AC74E-NG compatible with other logic families?
Yes, the CD74AC74E-NG in the AC logic family is compatible with TTL logic levels and can interface directly with most 5V digital systems. It can also work alongside HC, HCT, and standard CMOS families with appropriate level-shifting where supply voltages differ.
