MAX14979EETX+

The MAX14979EETX+ is a high bandwidth, ±15KV ESD protection LVDS switch in 36 pin TQFN package. This high speed passive switch provides LVDS signal routing for switchable graphics with extra ESD protection. It is optimized for high speed differential, 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 per MIL-STD-883, method 3015 and excellent high frequency response. These features make this device especially useful for interfaces that must go to an outside connection. It 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.
