The MPC508A is an 8-channel single-ended analog
multiplexer and the MPC509A is a 4-channel differential
multiplexer.
The MPC508A and MPC509A multiplexers have input
overvoltage protection. Analog input voltages may
exceed either power supply voltage without damaging
the device or disturbing the signal path of other channels.
The protection circuitry assures that signal fidelity
is maintained even under fault conditions that
would destroy other multiplexers. Analog inputs can
withstand 70Vp-p signal levels and standard ESD
tests. Signal sources are protected from short circuits
should multiplexer power loss occur; each input presents
a 1kW resistance under this condition. Digital
inputs can also sustain continuous faults up to 4V
greater than either supply voltage.
These features make the MPC508A and MPC509A
ideal for use in systems where the analog signals
originate from external equipment or separately powered
sources.
