The NXP 74HCT4040PW is a high-performance, 12-stage binary ripple counter integrated circuit, designed with advanced silicon-gate CMOS technology. It is part of the 74HCT family, which is known for its compatibility with TTL levels while maintaining CMOS low power consumption. This device features a fully static operation and includes a master reset input that clears the counter, setting all outputs low.

Key Features

• Logic Family: The 74HCT4040PW operates under the 74HCT logic family, providing TTL level compatibility while ensuring the benefits of CMOS technology, such as low power dissipation.
• Counter Type: It is a 12-stage binary ripple counter, which means that each stage divides the frequency of the input signal by two, making it suitable for frequency division applications and time-delay generation.
• Supply Voltage Range: This device operates on a supply voltage range from 4.5V to 5.5V, making it ideal for 5V logic systems.
• Package Type: The counter comes in a TSSOP16 (Thin Shrink Small Outline Package) with 16 pins, providing a compact footprint for space-constrained applications.
• High-Speed Operation: The 74HCT4040PW is capable of high-speed operation, ensuring quick response times and efficient performance in high-frequency counting applications.
• Master Reset: An asynchronous master reset input (MR) is included, which when set high, resets the counter to zero, regardless of the state of the clock input.

Applications

The versatility of the NXP 74HCT4040PW makes it suitable for a wide range of applications, including:

• Frequency division
• Time delay generation
• Counter/timer functions in microprocessor systems
• Sequential state machines
• Interface circuitry
• Pulse shaping and waveform generation

With its robust design and reliable performance, the NXP 74HCT4040PW is a preferred choice for designers who require a precision binary ripple counter for their digital projects.
