The **MHO+64TBD-R** is a specific part number typically associated with **Crystal Oscillators**, often manufactured by companies like MtronPTI. These components are critical for providing a stable clock signal in digital circuits. --- ### 1. Technical Specifications Based on the standard nomenclature for the MHO series, here is a breakdown of its core characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Usually "Full Size" | | **Output Type** | TTL / HCMOS Compatible | | **Supply Voltage** | Typically 5.0V (Standard for MHO series) | | **Frequency Stability** | Usually ±50ppm or ±100ppm (depending on the "B" or "C" suffix) | | **Operating Temperature** | 0°C to +70°C (Standard Commercial) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown The alphanumeric string defines the physical and electrical properties of the part: 1. **MHO**: Represents the series (Metal Thru-Hole Oscillator). 2. **+**: Often indicates a specific lead-free or enhanced processing designation. 3. **6**: Refers to the supply voltage (In this series, 6 often denotes 5.0V). 4. **4**: Refers to the frequency stability (e.g., 4 = ±50 ppm). 5. **T**: Represents the output type (T = TTL/HCMOS). 6. **BD**: This usually refers to the specific frequency or internal factory codes. 7. **-R**: RoHS Compliant (Lead-free). --- ### 3. Pin Configuration For a standard 14-pin DIP package crystal oscillator, only four pins are typically functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | Positive Supply Voltage (+5.0V) | --- ### 4. Common Applications * **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. * **Networking Hardware:** Used in routers and switches for data timing. * **Industrial Control:** Timing for PLC (Programmable Logic Controllers). * **Legacy Systems:** Many older 8-bit and 16-bit systems rely on these 14-pin DIP oscillators.
