TEXAS INSTRUMENTS MPC508AUG4 芯片, 16通道模拟多路复用器
The is an 8-channel single-ended Analog Multiplexer. The 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 1kR resistance under this condition. Digital inputs can also sustain continuous faults up to 4V greater than either supply voltage. The device is fabricated with BurrBrown"s dielectrically isolated CMOS technology.
