The **MHO+44TAAD-R** is a specific part number typically associated with **MHO+ series crystal oscillators** manufactured by companies like MtronPTI. These components are used to provide precise timing signals in electronic circuits. --- ### 1. Component Specification Overview Below is a breakdown of the typical technical characteristics for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) | | **Frequency Range** | Usually fixed (defined by specific sub-codes) | | **Output Type** | CMOS / TTL Compatible | | **Operating Voltage** | 5.0V (Standard for MHO series) | | **Stability** | ±100ppm to ±25ppm (depending on grade) | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "MHO" designation generally follows this logic: * **MHO:** Series designation (Metal thru-hole oscillator). * **44:** Often refers to the frequency stability and operating temperature range (e.g., ±100ppm, 0°C to +70°C). * **T:** Usually indicates the output load or symmetry (e.g., TTL/CMOS compatible). * **AA:** Internal factory code for specific revisions or mechanical variants. * **D:** Often signifies a "Tri-state" function (Enable/Disable pin). * **-R:** RoHS Compliant (Lead-free). --- ### 3. Pin Configuration For a standard 14-pin DIP package (where only 4 pins are active): | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-State | Enable/Disable control | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | Clock Signal Output | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Common Applications These oscillators are "legacy" style components often found in: 1. **Industrial Control Systems:** Where through-hole components are preferred for durability. 2. **Legacy Computing:** Motherboards or expansion cards requiring a master clock. 3. **Communication Equipment:** Synchronizing data transmission between modules. 4. **Test & Measurement:** Providing a stable reference frequency for counters or timers.
