CMOS technology. The multiplexers are available in plastic DIP and plastic SOIC packages. Temperature range is –40°C to +85°C.
FUNCTIONAL DIAGRAMS
DESCRIPTION
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 over
voltage 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 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 and MPC509A ideal for use in systems where the analog signals originate from external equipment or separatel...
