The **MHO+41TAD-R** is a specific type of **Crystal Oscillator** (often referred to as a Clock Oscillator). It is commonly used in digital circuits to provide a stable frequency reference. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications The MHO series is typically manufactured by companies like **MtronPTI**. These components are known for their reliability in industrial and telecommunications applications. | Feature | Specification Details | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size or Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Standard Frequency** | Varies by sub-model (Commonly in MHz range) | | **Supply Voltage ($V_{cc}$)** | Typically 5.0V (Standard for the 'T' series) | --- ### 2. Part Number Breakdown The alphanumeric code provides specific information about the component's hardware configuration: * **MHO:** Series designation (Metal thru-hole oscillator). * **+:** Usually indicates RoHS compliance (lead-free). * **4:** Stability code (Often refers to ±50ppm or ±100ppm stability). * **1:** Operating temperature range (Often 0°C to +70°C). * **T:** Output type (TTL/HCMOS compatible). * **A:** Duty Cycle (Usually 40/60% or 45/55%). * **D:** Tri-state Enable/Disable function (allows the output to be turned off electronically). * **R:** Frequency stability or specific revision indicator. --- ### 3. Pin Configuration Since this is a 4-pin device housed in a 14-pin DIP footprint (where only 4 pins are present), the layout is standard: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **Enable/Disable** | High or Open = Output Active; Low = High Impedance | | **7** | **Ground** | Case Ground / Negative supply | | **8** | **Output** | The clock signal (Square wave) | | **14** | **$V_{cc}$** | Positive Supply Voltage (+5.0V) | --- ### 4. Key Electronic Characteristics * **Stability:** Unlike a simple 2-pin crystal, this is an active component. It includes the crystal and the oscillation circuitry inside a hermetically sealed metal can, which protects it from electromagnetic interference (EMI). * **Tri-state Function:** Pin 1 allows the oscillator to be "disconnected" from the bus without powering down the device, which is useful for testing or power-saving modes. * **Load Drive:** It is designed to drive standard capacitive loads (usually 15pF to 50pF) typical of CMOS logic gates. ---
