The **MHO+26TBD-R** is a specific part number typically associated with **MHO+ Series Clock Oscillators** manufactured by providers like MtronPTI. These components are critical for providing a stable frequency reference in digital circuits. --- ### 1. Part Number Breakdown Based on standard industry naming conventions for the MHO series, the alphanumeric code can be decoded as follows: | Segment | Feature | Description | | :--- | :--- | :--- | | **MHO+** | Series Type | High-reliability, 14-pin DIP compatible (though often 4-pin) Crystal Oscillator. | | **2** | Supply Voltage | Usually indicates **5.0V** (standard) or **3.3V** operation. | | **6** | Stability/Temp | Represents frequency stability (e.g., ±50ppm or ±100ppm) over a specific range. | | **T** | Output Type | **TTL / HCMOS** compatible output. | | **B** | Duty Cycle | Often indicates a 40/60% or 45/55% tight symmetry. | | **D** | Tri-state Function | Includes an "Enable/Disable" function on Pin 1. | | **R** | RoHS Compliance | Lead-free and compliant with environmental regulations. | --- ### 2. Key Technical Specifications While specific datasheets should be consulted for exact frequency values (usually measured in MHz), the general specifications for this series include: * **Frequency Range:** Typically 1.000 MHz to 150.000 MHz. * **Package Style:** Through-hole (DIP) or SMD, often in a metal "half-size" or "full-size" can to reduce EMI. * **Operating Temperature:** Generally -10°C to +70°C (Commercial) or -40°C to +85°C (Industrial). * **Output Load:** 15pF to 50pF (HCMOS). --- ### 3. Pin Configuration For the standard 4-pin "Half-Size" DIP package common to this series: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Tri-state (INH) | High or Open = Output Active; Low = High Impedance. | | **7** | Case Ground | Connected to the metal cover to minimize noise. | | **8** | Output | The generated clock signal (Square wave). | | **14** | Vcc | Positive supply voltage (+5V or +3.3V). | --- ### 4. Applications The MHO+26TBD-R is used in environments requiring a robust, through-hole timing solution: * **Legacy Computing:** Motherboards and peripheral controllers. * **Industrial Control:** PLCs and automation hardware. * **Networking:** Routers and switches requiring a stable HCMOS clock. * **Test Equipment:** Oscilloscopes and signal generators.
