STMicroelectronics HCF4013BE Dual D-Type Flip-Flop
The HCF4013BE from STMicroelectronics is a high-performance integrated circuit that features two independent D-type flip-flops with individual set and reset inputs. This versatile component is designed to be used in a wide range of applications, including control systems, data storage, frequency division, and flip-flop-based operations.
Each flip-flop has its own dedicated set (S) and reset (R) inputs, which are asynchronous, allowing for immediate setting or resetting of the flip-flop. The D (data) input and the Q (output) and Q̅ (inverted output) provide synchronous control of the flip-flop state. The flip-flop changes state on the positive-going transition of the clock (CLK) input, making it suitable for edge-triggered applications.
The HCF4013BE operates over a wide voltage range from 3V to 15V and offers low power consumption, which makes it ideal for battery-operated devices. Its high noise immunity and low power dissipation are achieved through the use of MOS technology. The device is characterized for operation from -55°C to +125°C, ensuring reliable performance in extreme conditions.
This dual D-type flip-flop is encapsulated in a 14-pin dual in-line package (DIP), which is a common package type for easy insertion into standard breadboards and sockets. The pin configuration is designed for simple and straightforward implementation in various digital circuits.
Key features of the HCF4013BE include:
- Medium-speed operation: Typical clock toggle rate of 16 MHz at 10V
- Standardized, symmetrical output characteristics
- High noise immunity: 0.45 VDD (typical)
- Low power dissipation: 1 µW (max) at 25°C
- 100% tested for quiescent current at 20V
- Static flip-flop operation - retains state indefinitely with clock level either high or low
Whether you are designing a new digital system or troubleshooting an existing one, the HCF4013BE is an excellent choice for a reliable and flexible D-type flip-flop. Its robustness and ease of use make it a staple in the toolbox of electronics engineers and hobbyists alike.
