MP C50 6 MP MPC506A MPC507A C50 7 SBFS018A – JANUARY 1988 – REVISED OCTOBER 2003 www.datasheet4u.com Single-Ended 16-Channel/Differential 8-Channel CMOS ANALOG MULTIPLEXERS FUNCTIONAL DIAGRAMS FEATURES q ANALOG OVERVOLTAGE PROTECTION: 70VPP q NO CHANNEL INTERACTION DURING OVERVOLTAGE q BREAK-BEFORE-MAKE SWITCHING q ANALOG SIGNAL RANGE: ±15V q STANDBY POWER: 7.5mW typ q TRUE SECOND SOURCE In 16 In 2 1kΩ 1kΩ In 1 1kΩ Out Decoder/ Driver DESCRIPTION The MPC506A is a 16-channel single-ended analog multiplexer, and the MPC507A is an 8-channel differential multiplexer. The MPC506A and MPC507A 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 1kΩ resistance under this condition. Digital inputs can also sustain 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 BurrBrown’s dielectrically isolated CMOS technology. The ...
