The **4052G-P16-R** is a specific part number typically associated with a **Dual 4-Channel Analog Multiplexer/Demultiplexer**. It is a CMOS logic device equivalent to the industry-standard 74HC4052 or CD4052 series. ### 1. General Overview The device functions as a digitally controlled analog switch. It features low "ON" impedance and very low "OFF" leakage current. It can handle both digital and analog signals (such as audio or sensor data) within the range of the power supply voltages. --- ### 2. Technical Specifications Below are the typical technical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Logic Type** | Multiplexer / Demultiplexer | | **Configuration** | Dual 4:1 Channel | | **Supply Voltage (Vcc)** | 2.0V to 10V (varies by manufacturer) | | **Package Type** | DIP-16 or SOP-16 (P16 suffix usually denotes pin count) | | **Operating Temperature** | -40°C to +85°C | | **On-Resistance (Ron)** | ~80 - 280 $\Omega$ (depending on Vcc) | --- ### 3. Pin Configuration (P16) The "P16" in the part number indicates a 16-pin package. Here is the standard functional layout: 1. **X0, X1, X2, X3**: Input/Output pins for Channel X. 2. **Y0, Y1, Y2, Y3**: Input/Output pins for Channel Y. 3. **X, Y**: Common pins (Common Out/In for X and Y). 4. **A, B**: Binary Address Select pins (Determines which channel is active). 5. **Inhibit (INH)**: Enable/Disable pin (High = all switches off). 6. **Vee**: Negative supply voltage (allows for bipolar/AC signals). 7. **Vss**: Ground. 8. **Vcc**: Positive supply voltage. --- ### 4. Logic Truth Table The selection of the channel is determined by the binary state of pins A and B: | INH | B | A | Active Channel | | :---: | :---: | :---: | :--- | | L | L | L | X0, Y0 | | L | L | H | X1, Y1 | | L | H | L | X2, Y2 | | L | H | H | X3, Y3 | | H | X | X | None (Disconnected) | --- ### 5. Common Applications * **Analog Signal Routing**: Switching between different sensor inputs to a single ADC pin on a microcontroller. * **Audio Switching**: Channel selection in stereo equipment. * **Digital Signal Multiplexing**: Routing communication lines (like UART or I2C) to multiple peripherals. * **Programmable Gain Amplifiers**: Using the switch to change resistor values in an Op-Amp feedback loop.
