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 70VPP signal levels and standard ESD tests. Signal sources are protected from short circuits should multiplexer power loss occur; each input presents a 1k Ω 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. The MPC508A and MPC509A 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 °C to +85°C. MPC508 MPC509 |
