Overview of NXP PC74HCT74P
The NXP PC74HCT74P is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). It is fabricated with silicon gate C2MOS technology and is specifically designed to operate from a 4.5 to 5.5 V power supply, making it suitable for a wide range of applications in the industrial and commercial markets.
Key Features
- Dual D-type flip-flop: The PC74HCT74P contains two independent D-type flip-flops with set and reset capabilities, which are essential for a variety of sequential logic operations.
- Logic Level Compatibility: This device can be driven by TTL output levels, as it has input levels that are compatible with TTL output levels.
- High Noise Immunity: The true and complementary outputs provide high noise immunity and balanced propagation delays.
- Output Drive Capability: It can drive up to 10 LSTTL loads, ensuring sufficient power to drive connected components.
Functional Description
The PC74HCT74P's flip-flops have direct clear and preset inputs. Information on the data (D) input is accepted by the flip-flops on the positive-going edge of the clock pulse. Following the hold time interval, data at the D-input can be changed without affecting the levels at the outputs. The clear and preset inputs are asynchronous, with clear being active low and preset being active high.
Applications
Thanks to its robust design and high-speed operation, the NXP PC74HCT74P is ideal for use in:
- Counters and dividers
- Registers
- Control circuits
- Toggle circuits
Package and Quality
The device comes in a 14-pin DIP (Dual In-line Package), making it easy to integrate into a wide variety of circuit boards. NXP's commitment to quality ensures that the PC74HCT74P meets stringent standards, providing reliable performance for critical applications.
With its combination of speed, power efficiency, and compatibility, the NXP PC74HCT74P is an excellent choice for designers looking to implement reliable flip-flops in their digital logic systems.
