HI3-0508A-5Z (RENESAS)

The HI3-0508A-5Z is a single 8-channel Multiplexer with active overvoltage protection. Analog input levels may greatly exceed either power supply without damaging the device or disturbing the signal path of other channels. Active protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. Digital inputs will also sustain continuous faults up to 4V greater than either supply. In addition, signal sources are protected from short circuiting should multiplexer supply loss occur. Each input presents 1kR of resistance under this condition. The device is fabricated with 44V dielectrically isolated CMOS technology.
