### Overview of ADG774ABCPZ-R2 The **ADG774ABCPZ-R2** is a high-performance, monolithic CMOS device containing four independently selectable 2:1 multiplexers/demultiplexers. It is designed by Analog Devices and is widely known for its high bandwidth and low power consumption. --- ### Technical Specifications The following table outlines the primary electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Switch Configuration** | Quad 2:1 Multiplexer (SPDT x 4) | | **Supply Voltage (Single)** | 3.3 V to 5 V | | **Bandwidth (-3 dB)** | 400 MHz | | **On-Resistance ($R_{ON}$)** | 2.2 $\Omega$ (Typical) | | **On-Resistance Flatness** | 0.5 $\Omega$ | | **Package Type** | LFCSP-16 (Lead Frame Chip Scale Package) | | **Operating Temperature** | -40°C to +125°C | | **Propagation Delay** | 0.25 ns | --- ### Key Electronic Features #### 1. Low On-Resistance ($R_{ON}$) With a typical resistance of only **2.2 $\Omega$**, this part minimizes signal distortion and voltage drops across the switch. This is critical for maintaining signal integrity in high-speed data paths. #### 2. High Bandwidth Supporting up to **400 MHz**, the ADG774 is suitable for switching high-speed signals such as video, USB 1.1, and fast data bus signals without significant attenuation. #### 3. Fast Switching Times The device offers very low propagation delays and fast switching speeds ($t_{ON}$ and $t_{OFF}$), ensuring rapid transitions between different signal sources. #### 4. Low Power Consumption Built on a submicron CMOS process, the device consumes minimal power, making it ideal for portable or battery-powered electronic applications. --- ### Pin Configuration & Functionality The **LFCSP-16** package provides a compact footprint. The pins are generally categorized as follows: * **S1A to S4B:** Source terminals (Input/Output). * **D1 to D4:** Drain terminals (Common Output/Input). * **IN:** Digital control input that selects which source is connected to the drain. * **$\overline{EN}$ (Enable):** Active-low digital input. When high, all switches are in the OFF state. * **$V_{DD}$ / GND:** Power supply and ground pins. --- ### Typical Applications * **High-Speed Signal Routing:** Switching between different clock sources or data streams. * **Video Switching:** Used in RGB or composite video routing due to low distortion. * **Communication Systems:** Data acquisition and baseband signal switching. * **USB Switching:** Routing USB signals in multi-port environments.
