The MAX4818/MAX4819 high-bandwidth, low-on-resistance analog dual SPDT switches/4:1 multiplexers are designed to serve as integrated T1/E1 protection.
Features
* Dual SPDT and 4:1 Multiplexer Configurations
* Dual-Supply Operation from ±3.3V to ±5V
* Single-Supply Operation from +6V to +11V
* Hot-Insertion Tolerant with No DC Path to the Supplies
* Low On-Resistance, RON = 4Ω (typ) and 6Ω (max)
* Over 350MHz
Applications
* Each MAX4818/MAX4819 replaces four electromechanical relays, significantly reducing board space, simplifying PC board routing, and reducing power consumption. These devices operate with ±3.3V or ±5V dual supplies for applications requiring T1/E1 signal switching in the line side of the interface tr
