### 2. Pin Configuration (DIP-14 Style)
Since this is a standard "Metal Can" oscillator, the pinout follows a universal industrial layout:
* **Pin 1:** NC (No Connection) or Tri-state Control (Enable/Disable).
* **Pin 7:** Case Ground (GND).
* **Pin 8:** Output Signal (The clock frequency).
* **Pin 14:** Supply Voltage (Vcc / +5V).
---
### 3. Key Features
* **Hermetically Sealed:** The internal quartz crystal is housed in a metal "Can" package to protect it from moisture and atmospheric interference.
* **Integrated Driver:** Unlike a passive 2-pin crystal, this is an **active** component. It contains the oscillating circuit and buffer internally; you only need to provide power to get a square wave output.
* **RoHS Compliant:** The "-R" suffix at the end of the part number typically signifies **RoHS Compliance** (Lead-free).

### 4. Typical Applications
These oscillators are used in legacy and industrial hardware where a reliable, high-voltage (5V) clock source is required:
1. **Microprocessor Clocks:** Providing the heartbeat for 8-bit or 16-bit CPUs.
2. **Communication Ports:** Timing for RS-232 or Ethernet controllers.
3. **Industrial Control:** Embedded systems in manufacturing equipment.
