The **42VN-R** is a specific electronic component identifier typically associated with **SMD (Surface Mount Device)** logic gates or integrated circuits, most commonly manufactured by **Toshiba** or **Nexperia**. Specifically, this code usually points to a **Low-Voltage CMOS Logic Gate**, often the **74VHC1G08** or a similar high-speed buffer/logic chip in a small footprint package. --- ### 1. Key Technical Specifications The following table outlines the typical characteristics of parts marked with or belonging to the 42VN-R family (based on the 74VHC1G series): | Feature | Specification | | :--- | :--- | | **Logic Type** | 2-Input AND Gate (typically) | | **Technology** | CMOS (Low Power) | | **Voltage Range ($V_{CC}$)** | 2.0V to 5.5V | | **Operating Temperature** | -40°C to +85°C | | **Input Type** | Over-voltage tolerant (up to 7V) | | **Output Current** | 8mA (at 5V) | | **Propagation Delay** | ~3.7ns (at 5V) | --- ### 2. Physical Characteristics & Packaging The "42VN-R" nomenclature is often found on these specific package types designed for high-density circuit boards: * **Package Type:** SOT-23-5, SSOP5, or SC-70-5 (USV/fV). * **Size:** Extremely small footprint (approx. 2.0mm x 2.1mm). * **Mounting:** Surface Mount (SMD/SMT). * **Pin Count:** 5 Pins (Input A, Input B, Ground, Output Y, $V_{CC}$). --- ### 3. Common Usage Scenarios These parts are used for localized logic functions where a large multi-gate IC would waste space. * **Signal Conditioning:** Squaring up weak signals before they reach a microprocessor. * **Enable/Disable Logic:** Controlling the power-on sequence of larger modules. * **Mobile Electronics:** Due to the low power consumption and tiny size, they are ubiquitous in smartphones and tablets. * **Level Shifting:** Interfacing between different voltage domains (e.g., 3.3V to 5V). --- ### 4. Part Number Breakdown (Generic) While the exact marking "42VN" is a shorthand code, it typically translates to: ```text 42 -> Device Function Code (e.g., AND Gate) V -> Voltage Family (VHC / Very High Speed) N -> Package Designator R -> Tape and Reel Packaging indicator ``` ---
