DESCRIPTION

The MPC506A is a 16-channel single-ended analog multiplexer,

and the MPC507A is an 8-channel differential multiplexer.

The MPC506A and MPC507A 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 70VPP signal levels and standard ESD

tests. Signal sources are protected from short circuits should

multiplexer power loss occur; each input presents a 1kΩ

resistance under this condition. Digital inputs can also sustain

continuous faults up to 4V greater than either supply

voltage.

These features make the MPC506A and MPC507A ideal for

use in systems where the analog signals originate from

external equipment or separately powered sources.

The MPC506A and MPC507A are fabricated with Burr-

Brown’s dielectrically isolated CMOS technology. The multiplexers

are available in plastic DIP and plastic SOIC packages.

Temperature range is –40/+85°C.
