SN74AC74D Dual D-Type Positive Edge-Triggered Flip-Flop
The SN74AC74D from Texas Instruments is a high-speed, dual positive-edge-triggered D-type flip-flop integrated circuit. It is designed to operate from 2 V to 6 V, making it suitable for a wide range of applications, including those that require low power consumption and high-speed operation.
This flip-flop features two independent D-type flip-flops with individual clear and preset inputs for each flip-flop. The clear and preset inputs are active low, allowing for asynchronous control of the state of the flip-flop. The flip-flops are positive edge-triggered, meaning they change state on the rising edge of the clock input signal.
The SN74AC74D is commonly used in applications requiring data storage, data synchronization, and the elimination of metastable conditions. It is a versatile component that can be implemented in a variety of digital circuits, such as frequency dividers, shift registers, and state machines. The device is characterized for operation from -40°C to 85°C, making it reliable for use in industrial environments.
Key features of the SN74AC74D include:
- Two independent D-type flip-flops with direct clear and preset inputs
- Edge-triggered from a low-to-high transition of the clock pulse
- Wide operating voltage range of 2 V to 6 V
- Outputs can drive up to 24 mA at 5 V
- Typical tpd of 4.5 ns at 5 V
- Low power consumption
- Available in industry-standard 14-pin SOIC package
For designers and engineers, the SN74AC74D provides a reliable solution for sequential logic operations. Its fast switching speeds and low power consumption make it an excellent choice for both battery-powered and high-speed systems. The device's small footprint also makes it ideal for space-constrained applications.
