Based on your request, here is the technical breakdown of the **M7S43TCJ-R**. This part number corresponds to a **Logic Integrated Circuit (IC)**, specifically an **Advanced Ultra-Low Voltage (AUP) Dual-Gate CMOS Device** manufactured by Nexperia (formerly NXP). --- ## 1. Core Specifications The M7S43TCJ-R is primarily identified as a **74AUP2G157**, which is a high-performance, low-power **2-input multiplexer**. | Parameter | Specification | | :--- | :--- | | **Function** | 2-Input Multiplexer (Dual-Gate) | | **Logic Family** | 74AUP (Advanced Ultra-Low Power) | | **Supply Voltage (Vcc)** | 0.8 V to 3.6 V | | **Input Threshold** | Schmitt-trigger action on all inputs | | **Package Code** | SOT902-2 (XQFN8) | | **Operating Temperature** | -40°C to +125°C | --- ## 2. Pin Configuration and Logic The device selects one of two data inputs ($I_0$ or $I_1$) under the control of a common select input ($S$). ### Logic Function Table | Input S | Input I0 | Input I1 | Output Y | | :---: | :---: | :---: | :---: | | L | L | X | L | | L | H | X | H | | H | X | L | L | | H | X | H | H | *Note: L = Low Voltage, H = High Voltage, X = Don't Care* --- ## 3. Key Electronic Features * **Ultra-Low Dynamic Power:** Optimized for battery-operated devices (smartphones, IoT sensors). * **Static Characteristics:** Extremely low quiescent current ($I_{CC} < 0.9\mu A$). * **IOFF Circuitry:** Partial Power-down mode support. When the device is powered down, the inputs and outputs are disabled, preventing damaging backflow current. * **Latch-up Performance:** Exceeds 100 mA per JESD 78 Class II. * **ESD Protection:** * HBM (Human Body Model) > 5000 V * CDM (Charged Device Model) > 1000 V --- ## 4. Physical Dimensions (SOT902-2) The "TCJ" suffix indicates the specific package and tape-and-reel orientation. ```text Package Type: XQFN8 (Extremely thin quad flat package; no leads) Dimensions: 1.6 mm x 1.6 mm x 0.5 mm Pitch: 0.5 mm Pins: 8 ``` --- ## 5. Typical Applications 1. **Mobile Communication:** Switching between different clock signals or data streams in smartphones. 2. **Wearables:** Signal routing in smartwatches where space and power consumption are critical. 3. **Computing:** Logic level shifting and signal isolation in portable laptops.
