MAX355 Maxim, MAX355 Datasheet - Page 11

• Manufacturer Part Number: MAX355
• Description: The MAX354/MAX355 fault-protected multiplexers (muxes) use a series N-channel, P-channel, N-channel structure that protects the devices from overvoltage up to 40V beyond the supply rails during power-up, power-down, and fault conditions
• Manufacturer: Maxim
