The **MHO+76TAD-R** is a specific part number typically associated with **MHO+ Series Crystal Oscillators** manufactured by companies like **MtronPTI**. These components are precision frequency control devices used in various electronic timing circuits. --- ## Technical Specifications Based on the standard nomenclature for the MHO series, here is the breakdown of the electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard for this series) | | **Frequency Stability** | ±100 ppm (Standard) to ±25 ppm (Tight) | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | "R" suffix indicates RoHS Compliant | --- ## Part Number Breakdown To understand the specific electronic behavior, we can deconstruct the code: 1. **MHO+**: Indicates the product series (High-speed CMOS/TTL compatible crystal oscillators in a metal package). 2. **7**: Refers to the Voltage Supply (usually 5.0V). 3. **6**: Typically denotes the Frequency Stability (e.g., ±25ppm or ±50ppm depending on the specific datasheet revision). 4. **T**: Stands for the **Tristate** function. This allows the output to be placed in a high-impedance state, effectively "disconnecting" it from the circuit without powering it down. 5. **AD**: Often refers to the Duty Cycle (e.g., 40/60% or 45/55% symmetry). 6. **R**: Indicates **RoHS Compliance** (Lead-free). --- ## Pin Configuration (Standard 14-pin DIP) Though it has 14 pins physically, most are missing/unused. Usually, only 4 pins are connected: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tristate control) | | **7** | GND | Circuit Ground | | **8** | Output | Frequency Signal Output | | **14** | Vcc | +5.0V Power Supply | --- ## Key Applications * **Microprocessor Clocks:** Providing the "heartbeat" for CPUs and Microcontrollers. * **Networking Gear:** Used in switches and routers for data synchronization. * **Legacy Hardware:** Commonly found in older industrial equipment due to the 14-pin DIP form factor. * **Test & Measurement:** Stable frequency reference for laboratory instruments.
