MAX378 Datasheet (Maxim) - High-Voltage / Fault-Protected Analog Multiplexers

MAX378, High-Voltage / Fault-Protected Analog Multiplexers

The MAX378 8-channel single-ended (1-of-8) multiplexer and the MAX379 4-channel differential (2-of-8) multiplexer use a series N-channel/P-channel/N-channel structure to provide significant fault protection.

If the power supplies to the MAX378/MAX379 are inadvertently turned off while input voltages
