The HEF4528BP is a monolithic, high-quality integrated circuit produced by NXP Semiconductors. This versatile component is part of the CMOS 4000 series, renowned for its low power consumption and high noise immunity. It is specifically designed as a Dual Monostable Multivibrator, making it an essential part of various timing applications.

Key Features

• Voltage Range: The device operates over a recommended voltage range of 3V to 15V, providing flexibility for different power requirements and ensuring compatibility with both TTL (Transistor-Transistor Logic) and high-speed CMOS logic levels.
• Dual Functionality: As a dual monostable multivibrator, the HEF4528BP contains two independent monostable multivibrators in a single package. This allows for the creation of two separate timing circuits, which can be used in sequence or configured for more complex timing solutions.
• Adjustable Timing: The timing periods for each multivibrator can be set by external components (capacitors and resistors), offering a wide range of adjustability to suit various applications.
• Trigger Types: It features both positive and negative edge triggering, providing versatile triggering options to designers.
• Output Pulse Width: The output pulse width is determined by the external timing components and remains constant regardless of input pulse duration.
• Re-triggerable: The multivibrators are re-triggerable, allowing for the extension of the output pulse duration with successive inputs before the completion of the timing cycle.

Applications

The HEF4528BP is used in various applications, including but not limited to:

• Timing circuits
• Pulse shaping
• Missing pulse detection
• Sequential timing
• Delay lines
