CD74HC4538E Description

CD74HC4538E Description

The CD74HC4538E from Texas Instruments is a high-speed dual retriggerable/resettable monostable multivibrator from the 74HC series, designed for precision timing applications. Housed in a 16-pin DIP (Through Hole) package, it operates over a 2V to 6V supply range, making it compatible with both 3.3V and 5V systems. With a propagation delay of just 21ns and Schmitt-trigger inputs, it ensures noise immunity and reliable performance in noisy environments. The device is ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.

CD74HC4538E Features

  • Dual Independent Circuits: Two monostable multivibrators in one package, enabling flexible timing configurations.
  • Retriggerable/Resettable Operation: Supports dynamic retriggering and external reset for precise control.
  • Schmitt-Trigger Inputs: Enhances noise rejection and signal integrity.
  • Wide Voltage Range (2V–6V): Suitable for mixed-voltage systems.
  • High Output Drive (5.2mA): Capable of driving moderate loads directly.
  • Low Power Consumption: Optimized for energy-efficient designs.
  • Through-Hole Mounting: Ideal for prototyping and industrial applications requiring robust mechanical connections.

CD74HC4538E Applications

This IC excels in applications requiring accurate pulse generation and timing control, such as:

  • Industrial Automation: Time-delay circuits, sensor debouncing.
