Overview of NXP PC74HCT174P

The NXP PC74HCT174P is a high-speed Si-gate CMOS device that belongs to the 74HCT family of integrated circuits. This particular chip is a hex D-type flip-flop with clear functionality, designed to offer a perfect blend of speed and power efficiency, making it suitable for a wide range of digital applications.

Key Features

• Logic Type: Hex D-type flip-flop with clear
• Logic Family: HCT
• Operating Voltage: 4.5V to 5.5V, which is compatible with TTL levels
• Output Current: High-level output current of -4 mA and low-level output current of 4 mA
• Pin Configuration: 16-pin DIP (Dual In-line Package)
• Temperature Range: Industrial range of -40°C to +85°C

Functionality

The PC74HCT174P contains six flip-flops with single-rail outputs. Each flip-flop is individually triggered by a low-to-high transition of the clock input while the clear input is held low. The clear input can terminate the state of the flip-flop asynchronously and is active low. This makes the device versatile for implementing synchronous state machines and temporary data storage in digital systems.

Applications

Due to its high-speed and efficient operation, the PC74HCT174P is used in various applications, including:

• Buffer storage
• Shift registers
• Data storage
• Pattern generators
• Counters and dividers

Compatibility

The HCT logic level of the PC74HCT174P allows it to interface with TTL logic levels, ensuring compatibility with older TTL devices while benefiting from CMOS technology's lower power consumption and increased noise immunity.
