The MC14538BDWG from ON Semiconductor is a high-performance, dual retriggerable/resettable monostable multivibrator. This integrated circuit (IC) is designed to offer precision timing capabilities, essential for a broad range of electronic applications. Featuring two independent monostable multivibrators in a single package, this device is a versatile component for timing, delay, gating, and pulse generation functions.

Key Features

• Wide Supply Voltage Range: The MC14538BDWG operates over a supply voltage range from 3 V to 15 V, making it suitable for interfacing with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic levels.
• Retriggerable/Resettable Functionality: Each multivibrator can be triggered by either a rising or falling edge of an input signal, and the output pulse duration can be extended by retriggering the device. Additionally, the output can be reset to its initial state at any time.
• Adjustable Pulse Width: The output pulse width is determined by external timing components (resistor and capacitor), providing flexibility to generate a wide range of time delays.
• High Output Current: Capable of sourcing or sinking up to 100 mA, the MC14538BDWG can directly drive loads or interface with other logic families.
• Output Pulse Width Range: It offers a pulse width range from a few nanoseconds to several hours, accommodating various application requirements.
• Separate Reset Inputs: Each multivibrator has an individual reset input, allowing for precise control over the timing sequences.

Applications

The MC14538BDWG is ideal for application in timing circuits, pulse generators, delayed timers, and as a part of digital logic systems where accurate time delays or one-shot pulse generation is required. It is commonly used in industrial controls, instrumentation, and communication systems.

Package and Quality

Enclosed in a 16-pin SOIC (Small Outline Integrated Circuit) package, the MC14538BDWG ensures a compact footprint on printed circuit boards (PCBs). ON Semiconductor's commitment to quality is evident in this product's design and manufacturing, making it a reliable choice for both hobbyist and industrial applications.
