### 2. Part Number Breakdown (Decoding)
While naming conventions can vary slightly by manufacturer, the "MHO+76TAAG-R" string typically decodes as follows:
* **MHO+**: Product series (5.0V HCMOS/TTL Crystal Oscillator).
* **76**: Often represents the specific frequency stability or temperature range code.
* **T**: Indicates "Tri-state" functionality (allows the output to be disabled/disconnected).
* **AA**: Often refers to the frequency stability (e.g., ±100ppm, ±50ppm, or ±25ppm).
* **G**: Symbolizes the specific symmetry or duty cycle (usually 40/60%).
* **-R**: **RoHS Compliant**.

### 3. Electrical Characteristics
These parts are designed to drive high-speed digital logic circuits.
* **Frequency Range:** Typically available from 1.000 MHz to 150.000 MHz (Specific frequency is usually printed on the top of the can).
* **Operating Temperature:** Generally -40°C to +85°C (Industrial Grade) or 0°C to 70°C (Commercial).
* **Tri-state Function:**
* **Pin 1 High (or open):** Output is active.
* **Pin 1 Low:** High impedance (disabled), reducing power consumption.
* **Package Dimensions:** Large metal "DIP" style package, which provides excellent EMI shielding.

### 4. Typical Pinout (14-pin DIP style)
Though it has a 14-pin footprint, only 4 pins are physically present or connected:
| Pin Number | Function | Description |
| :--- | :--- | :--- |
| **1** | E/D or NC | Enable/Disable (Tri-state) or No Connect |
| **7** | GND | Case Ground |
| **8** | Output | The clock signal output |
| **14** | $V_{cc}$ | +5.0V Power Supply |

### 5. Common Applications
* **Networking Gear:** Switches and routers requiring stable clock references.
* **Legacy Hardware:** Industrial controllers that utilize 5V logic.
* **Test & Measurement:** Oscilloscopes and signal generators.
* **Data Communications:** Synchronizing high-speed data transfers.
