The **MHO+42FAD-R** is a specific series/part number typically associated with **Quartz Crystal Oscillators**, commonly manufactured by companies like **MtronPTI**. These components are used to provide a stable clock signal for digital circuits, microprocessors, and telecommunication hardware. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Fixed frequency output | | **Package Style** | 14-pin DIP (Half Size) | Often 4-pins used in a 14-pin footprint | | **Output Type** | HCMOS / TTL | Compatible with standard digital logic | | **Supply Voltage** | 5.0V (Standard) | Standard operating voltage for the MHO series | | **Stability** | ±100 ppm (Typical) | Frequency stability over temperature | | **Operating Temp** | 0°C to +70°C | Commercial grade temperature range | --- ### 2. Pin Configuration For the "Half-Size" 14-pin DIP package used in this series, only four pins are typically functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | Usually no connection or Output Enable | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated clock frequency signal | | **Pin 14** | Vcc | +5V Power Supply | --- ### 3. Key Features * **Hermetically Sealed:** The metal "can" package is resistance-welded to protect the quartz crystal from moisture and atmospheric contaminants. * **Thru-Hole Mounting:** Designed for traditional PCB mounting or socket insertion. * **Reliability:** High shock and vibration resistance suitable for industrial applications. --- ### 4. Circuit Integration Example To use this part in a digital circuit, a decoupling capacitor is recommended to filter power supply noise. ```cpp // Logic Representation of Clock Usage // Vcc (Pin 14) ---- [ 0.1uF Capacitor ] ---- GND (Pin 7) // Output (Pin 8) ---------------------------> MCU Clock In ``` ---
