| Function | Electrical Char. | Input Voltage | Current | RON | COFF | Isolation | Switching Speed | IDD | Lifetime | Controller | Packaging | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| MM1200 | 6xSPST | AC/DC | 79 V | 1 A | 1.0 Ω | 90 fF | 10 GΩ | <10 µs | < 10 µA | >3B cycles | Serial-to-Parallel Interface | 6 x 6 mm BGA |
The MM1200 is a 6-channel SPST high-performance signal relay that can be used for high-density signal switching applications in both AC and DC circuits and is meant to replace electromechanical signal relays or reed relays. Typical applications range from medical equipment, DC switch matrices/multiplexers, to test & measurement equipment.
The MM1200 is capable of 1.0 A per channel steady state, and delivers low on-state contact resistance and high off-state isolation with >3 billion switching cycles and <10µs switching times.
Each switch is Normally Open (NO) and individually controlled by a digital serial-to-parallel Interface. An external +5 VDC logic supply and high voltage +79 VDC bias source are required for the operation of the internal switch driver.
