### 1. Key Technical Specifications
The part number follows a specific nomenclature. Here is a breakdown of the typical characteristics for the MHO series:
| Parameter | Specification (Typical) |
| :--- | :--- |
| **Component Type** | XO (Crystal Oscillator) |
| **Package Style** | 14-pin DIP (Full size) / Through-hole |
| **Output Type** | HCMOS / TTL Compatible |
| **Voltage Supply** | 5.0V (Standard for MHO series) |
| **Frequency Range** | 1.0 MHz to 100.0 MHz (Specific to exact model) |
| **Operating Temperature** | -40°C to +85°C (Industrial Grade) |
| **RoHS Status** | Compliant (Indicated by the "R" suffix) |

### 2. Functional Features
The MHO+44TCG-R is designed for reliability in demanding environments. Its core features include:
* **Tight Stability:** These oscillators offer low parts-per-million (ppm) frequency drift over temperature changes.
* **Tri-State Functionality:** The "T" in the suffix often indicates **Tri-state** (Enable/Disable) capability. This allows the output to be placed in a high-impedance state, which is useful for testing or power-saving modes.
* **Rugged Construction:** Being a through-hole DIP package, it provides superior mechanical stability compared to small surface-mount devices (SMD) in high-vibration environments.
* **Hermetic Sealing:** The metal case is hermetically sealed to protect the internal quartz crystal from moisture and atmospheric contaminants.

### 3. Pin Configuration (Standard 14-Pin DIP)
While it uses a 14-pin footprint, only 4 pins are usually active:
| Pin Number | Function | Description |
| :--- | :--- | :--- |
| **1** | N/C or Tri-State | Enable/Disable control |
| **7** | Ground | Case and circuit ground |
| **8** | Output | Frequency output signal |
| **14** | Vcc | +5.0V Power Supply |

### 4. Common Applications
* **Networking Gear:** Routers, switches, and gateways requiring a steady heartbeat for data processing.
* **Industrial Control:** PLCs and automation equipment operating in wide temperature ranges.
* **Legacy Systems:** Replacement parts for older PCB designs that utilize full-size DIP oscillator sockets.
