Overview

The MAX354/MAX3558CTI+ 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. The MAX354/MAX3558CTI+ also protect sensitive circuit components against voltages near or beyond the normal supplies. The MAX354 single 8-channel mux and the MAX3558CTI+ dual 4-channel mux protect analog signals while operating from a single 4.5V to 36V supply or ±4.5V to ±18V dual supplies. These muxes have 350Ω on-resistance and can be used for demultiplexing as well as multiplexing. Input leakage current is less than 0.5nA at +25°C and less than 5nA at +85°C. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility without pull-up resistors. Break-before-make operation is guaranteed and power consumption is less than 1.5mW.
