The options are relays, multiplexers and demultiplexers, analog multiplexers
or FPGA devices.
Analog switches, analog multiplexers
, and low-power transistors are fabricated by subcontractors in Dresden, Germany and in Beijing, China.
Intended for use in precision instrumentation, Vishay, Intertechnology's DG Series of analog multiplexers
and switches have leakage currents ranging from 0.
While the 42 cameras distributed among the primary and in termediate schools feed into SecureLink, they also transmit through analog multiplexers
to time-lapse recorders.
