FUNCTIONAL DIAGRAMS

DESCRIPTION

The MPC506A is a 16-channel single-ended analog multi-

plexer, and the MPC507A is an 8-channel differential multi-

plexer.

The MPC506A and MPC507A multiplexers have input over-

voltage protection. Analog input voltages may exceed either

power supply voltage without damaging the device or dis-

turbing 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

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 sus-

tain 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 multi-

plexers are available in plastic DIP and plastic SOIC pack-

ages. Temperature range is –40/+85

°C.
