The **UCD40106BL-P14-R** is a specific electronic component, typically classified as a **Hex Schmitt Trigger Inverter**. This part is part of the 4000 series logic family, known for its wide operating voltage range and high noise immunity. Below is a detailed breakdown of its specifications and functions. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Logic Function** | Hex Inverter (6 independent gates) | | **Input Type** | Schmitt Trigger | | **Package Type** | TSSOP-14 (Thin Shrink Small Outline Package) | | **Logic Family** | CD4000 (CMOS) | | **RoHS Status** | Compliant (Lead-free) | --- ### 2. Key Electrical Characteristics The "BL" and "R" suffixes usually denote specific packaging and taping variations (e.g., Reel packaging). * **Operating Voltage ($V_{DD}$):** Typically 3V to 18V. * **Hysteresis Voltage ($V_H$):** Usually around 0.5V to 1.0V (at $V_{DD}=5V$), which allows it to convert slow-changing or noisy input signals into clean, jitter-free square waves. * **Low Power Consumption:** Being a CMOS device, it draws very little static current. * **High Noise Immunity:** Due to the Schmitt trigger inputs, it is highly resistant to input noise. --- ### 3. Pin Configuration (TSSOP-14) The device contains six independent inverters. Each gate takes an input ($A$) and provides an inverted output ($\bar{Y}$). | Pin Number | Function | Description | | :--- | :--- | :--- | | 1, 3, 5, 9, 11, 13 | **1A - 6A** | Inputs for Inverters 1 through 6 | | 2, 4, 6, 8, 10, 12 | **1Y - 6Y** | Outputs for Inverters 1 through 6 | | 7 | **GND** | Ground (0V) | | 14 | **Vcc/Vdd** | Positive Supply Voltage | --- ### 4. Common Applications * **Waveform Shaping:** Converting sine waves or slow-rising pulses into sharp square waves. * **Debouncing:** Removing "bounce" noise from mechanical switches or buttons. * **Oscillators:** Creating simple RC (Resistor-Capacitor) relaxation oscillators. * **Signal Conditioning:** Cleaning up noisy digital signals in industrial environments. --- ### 5. Part Number Breakdown While naming conventions vary slightly by manufacturer (e.g., Unisonic Technologies - UTC), the code generally breaks down as follows: * **UCD**: Manufacturer Prefix (often UTC). * **40106**: Core logic identity (Hex Schmitt Inverter). * **BL**: Halogen-free and Lead-free designation. * **P14**: TSSOP-14 Package. * **R**: Tape and Reel packaging.
