MAX14979E：High-Bandwidth, ±15kV ESD Protection LVDS Switch

High-Speed Passive Switches Provide LVDS Signal Routing for Switchable Graphics with Extra ESD Protection

The MAX14979E is optimized for high-speed differential switching applications. The device is ideal for low-voltage differential signal (LVDS) and low-voltage, positive emitter-coupled logic (LVPECL) switching applications. The MAX14979E provides enhanced electrostatic discharge (ESD) protection up to ±15kV and excellent high-frequency response, making this device especially useful for interfaces that must go to an outside connection. The MAX14979E provides extremely low capacitance (CON) as well as low resistance (RON) for low-insertion loss and bandwidth up to 650MHz (1.3Gbps). In addition to the four pairs of double-pole/double-throw (DPDT) switches, the MAX14979E provides low-frequency (up to 50MHz) and AUX switching that can be used for LED lighting or other applications. The MAX14979E is available in a space-saving, 36-pin TQFN package and operates over the extended -40°C to +85°C temperature range.
