MPC508A IC Chip

MPC508A(Single-Ended 8-Channel/Differential 4-Channel CMOS ANALOG MULTIPLEXERS）

Introduction

The MPC508A is an 8-channel single-ended analog multiplexer.

The MPC508A  multiplexer has 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 MPC508A ideal for use in systems where the analog signals originate from external equipment or separately powered sources.

The MPC508A is fabricated with Burr-Brown’s dielectrically isolated CMOS technology. The multiplexer is available in plastic DIP and plastic SOIC packages. Temperature range is -40°C to +85°C.
