Product Overview: 74LV74DB from NXP
The 74LV74DB is a high-performance, low-voltage dual D-type flip-flop integrated circuit designed and manufactured by NXP Semiconductors. This device is part of the 74LV family, which is known for its low-power consumption and high-speed operation, making it suitable for a wide range of digital applications.
Each flip-flop in the 74LV74DB has independent data (D), set (S), reset (R), and clock (CP) inputs, and Q and Q̅ outputs. The set and reset are asynchronous active LOW inputs and operate independently of the clock input. The flip-flops are positive-edge triggered, meaning that the state of the D input is captured at the moment of the rising edge of the clock and is transferred to the Q output on the next clock cycle.
Key Features:
- Low Voltage Operation: The device operates at a nominal voltage of 3.3V, which is compatible with TTL levels, allowing for easy integration into 3.3V systems without the need for level shifting.
- High Speed: The 74LV74DB offers high-speed performance, with typical clock-to-Q propagation delays of only 8.5ns at 3.3V, facilitating quick response times in digital circuits.
- Low Power Consumption: It has a low power dissipation, with a maximum ICC of only 80µA, making it an excellent choice for power-sensitive applications.
- Output Drive Capability: The device can drive up to 8 LSTTL loads, providing sufficient current to control multiple devices or LEDs.
- Multiple Package Options: The 74LV74DB is available in a variety of packaging options, including SO14, TSSOP14, and DHVQFN14, offering flexibility for different PCB layouts and space constraints.
Applications:
The versatility of the 74LV74DB makes it ideal for numerous applications, including:
- Counters and dividers
- Registers
- Control circuits
- Toggle circuits
- State machines
In conclusion, the 74LV74DB from NXP is a reliable and efficient choice for designers looking to implement dual D-type flip-flops in their digital systems. Its low voltage operation, high speed, and low power consumption, combined with the flexibility offered by multiple packaging options, make it an adaptable component for a diverse range of electronic applications.
