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
inputs can withstand 70V
PP
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 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.
