74HC74 Dual D Flip-Flop, Dip-14 Package
74HC74 Dual D Flip-Flop, DIP-14 Package
The 74HC74 is a dual D-type flip-flop integrated circuit from the high-speed CMOS logic family, housed in a standard 14-pin DIP package. Each flip-flop has independent data (D), clock (CLK), set (SD), and reset (RD) inputs, with complementary Q and Q̅ outputs. It is designed for use in digital counters, shift registers, and data storage applications.

What is the difference between the 74HC74 and the 74LS74?
The 74HC74 uses high-speed CMOS technology, offering lower power consumption and a wider supply voltage range (2V to 6V) compared to the 74LS74, which uses LS-TTL logic and operates at 5V only. The 74HC74 is also more suitable for battery-powered or 3.3V systems.
What payment options are available for the 74HC74 Dual D Flip-Flop?
You can pay using UPI (Google Pay, PhonePe, Paytm), debit/credit cards, or Cash on Delivery (COD). All payment options are available across India.
How do I use the set (SD) and reset (RD) pins on the 74HC74?
The SD and RD pins are active-low inputs. Pulling SD low sets the Q output high, while pulling RD low resets the Q output low. These pins are asynchronous, meaning they override the clock input. They should be tied to VCC if not used.
