MAX368CPN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX368CPN+ is a fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features a single 1 x 8:1 channel configuration housed in an 18-pin PDIP package with through-hole mounting. The device operates on a dual supply voltage ranging from ±4.5V to 18V, with a maximum operating voltage of 18V. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum run time of 1.5 µs, and a maximum break time of 1 µs. The component supports a maximum clock frequency of 1 MHz and draws a maximum power supply current of 2 mA. It functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix corresponds to the PDIP-18 package variant. Check for RoHS compliance status as historical data indicates potential non-compliance for this specific part number. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel 8:1 multiplexer with integrated fault protection and latch capability is required. Verify that the 1.8 kOhm on-resistance meets system impedance requirements. Ensure the dual supply voltage range aligns with available power rails. Consider the through-hole packaging constraint if surface-mount alternatives are preferred for high-volume production.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX368 series represents a family of analog multiplexers designed for robust signal switching in demanding environments. The CPN+ designation specifically identifies the commercial temperature grade version in a plastic dual in-line package. This part serves as a specialized interface component for connecting multiple sensors or signals to a single processing line while providing hardware-level protection against overvoltage or short-circuit events.
