## ADG3248BKS-R2: Electronic Component Overview The **ADG3248BKS-R2** is a high-performance, 2.5 V or 3.3 V, 2:1 multiplexer/demultiplexer (switch) designed by Analog Devices. It is built on a low-voltage CMOS process and is specifically utilized for bus switching and signal routing. --- ### 1. Key Technical Specifications Below is a summary of the primary electrical characteristics for this part: | Parameter | Specification | | :--- | :--- | | **Configuration** | 2:1 Mux/Demux (Single 8-Bit) | | **Supply Voltage (Vcc)** | 2.3 V to 3.6 V | | **On-Resistance (Ron)** | 8 $\Omega$ (Typical) | | **Propagation Delay** | < 250 ps | | **Package Type** | SC70 (6-lead) | | **Operating Temperature** | -40°C to +85°C | | **Input/Output Type** | Bidirectional | --- ### 2. Core Functional Components The internal architecture consists of the following electronic elements: * **N-Channel MOSFETs:** The core of the switch uses N-channel MOSFET technology. These provide low on-resistance and very low propagation delay, making them ideal for high-speed data buses. * **Level Shifting Logic:** The device is designed to handle different voltage levels. When the supply is at 3.3 V, it can interface with 2.5 V logic, providing a level-shifting function between disparate voltage domains. * **Control Logic (SEL Pin):** A single CMOS-compatible select input determines which path (S1 or S2) is connected to the common drain (D). * **ESD Protection:** Integrated circuitry protects the internal gates from electrostatic discharge, ensuring reliability in industrial environments. --- ### 3. Applications and Usage Due to its high speed and low resistance, the ADG3248 is commonly found in: 1. **Bus Switching:** Connecting a microprocessor to multiple peripherals. 2. **Voltage Translation:** Interfacing 3.3 V systems with 2.5 V systems. 3. **Memory Interleaving:** Switching between two memory banks at high speeds. 4. **Hot-Swap Applications:** The high impedance state during power-off prevents backflow of current, protecting sensitive components. --- ### 4.
