The **MHO+45TAAD-R** is a specific electronic component belonging to the **Crystal Oscillator** category, typically manufactured by companies like MtronPTI. These components are used to generate precise clock signals for digital circuits. --- ## Technical Specifications Below is a breakdown of the typical technical attributes for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package / Case** | 14-pin DIP (Through-Hole), Full Size | | **Frequency Range** | Usually custom-specified (e.g., 1.0 MHz to 150 MHz) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | 5.0V (Standard for MHO series) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±100ppm or ±50ppm (depending on sub-variant) | --- ## Key Features * **Through-Hole Design:** Uses a 14-pin DIP footprint (though often only 4 pins are physically present/connected), making it suitable for older industrial hardware or robust PCB designs. * **Hermetically Sealed:** The metal "can" package protects the quartz crystal from environmental humidity and atmospheric changes. * **Tri-state Functionality:** The "A" in the suffix often indicates an "Enable/Disable" function, allowing the oscillator output to be disconnected electronically to save power or perform testing. * **RoHS Compliant:** The "-R" suffix indicates that the part is compliant with Restriction of Hazardous Substances regulations (lead-free). --- ## Pinout Configuration In a standard 14-pin DIP oscillator like the MHO series, the internal connections are usually as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or E/D | No Connection or Enable/Disable Control | | **7** | GND | Ground / Negative Supply | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | +5.0V Power Supply | --- ## Common Applications 1. **Industrial Controls:** Providing timing for PLCs and automation hardware. 2. **Legacy Computing:** Serving as the master clock for older microprocessor systems. 3. **Networking:** Clocking for Ethernet controllers or communication interfaces. 4. **Test Equipment:** Stable frequency reference for measurement devices.
