Product Overview: 74HC221N by NXP Semiconductors

The 74HC221N is a high-speed Si-gate CMOS device from NXP Semiconductors designed to deliver the functionality of the industry-standard 74HC logic family with the speed and robustness required for modern digital circuits. This dual non-retriggerable monostable multivibrator with reset is a versatile component suitable for a wide range of timing and pulse generation applications.

Key Features

• Logic Type: Monostable Multivibrator - The 74HC221N is designed to generate a stable output pulse in response to an input trigger.
• Dual Channels: The device contains two independent channels, allowing for the implementation of two separate timing tasks within a single IC package.
• Non-Retriggerable: The output pulse duration is determined by external components, and the pulse does not extend with additional triggers during the pulse period.
• Reset Function: Each multivibrator has an active low reset input which can be used to terminate the output pulse at any time.
• Wide Operating Voltage: The 74HC221N operates within a voltage range of 2V to 6V, accommodating various power supply levels.
• Output Pulse Width Control: External resistor and capacitor components determine the pulse width, offering flexibility in timing adjustment.
• High Noise Immunity: The 74HC logic family is known for its high noise immunity, making the 74HC221N reliable in electronically noisy environments.
• Standard Pin Configuration: The device comes in a DIP-16 package, compatible with standard breadboards and sockets for easy prototyping and integration.
