CD74AC74E

The CD74AC74E is a dual D-type flip-flop integrated circuit from Harris Semiconductor, part of the AC logic family. Each flip-flop has independent set and reset inputs, and operates on a positive edge trigger. The device contains two elements, each with 1 bit, and provides complementary outputs. It operates over a supply voltage range of 1.5V to 5.5V, with a maximum clock frequency of 110 MHz. The propagation delay is 10 ns at 5V with 50 pF load. The quiescent current draw is only 4 µA, making it suitable for low-power applications. The device features ESD protection exceeding 2 kV per MIL-STD-883, Method 3015, and offers ±24 mA output drive capability with fanout to 15 F devices. It is housed in a 14-pin PDIP (0.300 inch, 7.62 mm) through-hole package, suitable for breadboard and prototyping. The operating temperature range is -55°C to 125°C, allowing use in extreme environments. This flip-flop is ideal for general-purpose register, storage, and timing applications in digital logic designs.
