The **UTM4052G-S08-R** is an integrated circuit (IC) primarily used as an **Analog Multiplexer/Demultiplexer**. It is a CMOS-based device designed to handle both analog and digital signals. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview The UTM4052G is a **Differential 4-Channel** device. This means it functions as a digitally controlled analog switch with two independent 4-channel selectors (Dual 4-to-1 configuration). ### 2. Technical Specifications | Parameter | Description | | :--- | :--- | | **Function** | Dual 4-Channel Analog Multiplexer/Demultiplexer | | **Supply Voltage (Vcc)** | 3.0V to 15V (Typical) | | **Package Type** | SOP-8 (Small Outline Package) | | **Configuration** | 2 x 4:1 Channels | | **Operating Temperature** | -40°C to +85°C | | **Control Logic** | Digital (High/Low) | ### 3. Pin Configuration (Typical for SOP-8) In the S08 (SOP-8) package, the pinout is condensed compared to standard 16-pin versions. The pins generally include: 1. **Common Out/In:** Where the selected signal is routed. 2. **Channel Inputs:** The four different paths for the signal. 3. **Address Pins (A, B):** Binary inputs used to select which channel is active. 4. **Vcc/GND:** Power supply pins. ### 4. Key Features * **Low "On" Resistance:** Minimizes signal loss and distortion when a channel is active. * **Wide Analog Signal Range:** Can handle signals up to the supply voltage. * **Bidirectional:** Signals can flow from the common pin to the channels (demux) or from channels to the common pin (mux). * **Low Crosstalk:** High isolation between channels to prevent interference. ### 5. Common Applications * **Signal Gating:** Routing specific sensor data to a single Analog-to-Digital Converter (ADC). * **Audio/Video Switching:** Selecting between different media input sources. * **Digital Logic:** Implementing complex logic functions or data routing in embedded systems. * **Communication Systems:** Used in telemetry and multiplexed data transmission. --- ### Comparison with UTM4051 and UTM4053 | Part Number | Configuration | Description | | :--- | :--- | :--- | | **UTM4051** | 8-to-1 | Single 8-channel multiplexer | | **UTM4052** | 4-to-1 (Dual) | Two 4-channel multiplexers | | **UTM4053** | 2-to-1 (Triple) | Three 2-channel multiplexers |
