MAX354CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354CPE+ is a fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features a single 8-channel configuration housed in a 16-pin Plastic DIP package. The device operates from a single supply of 4.5V to 36V or dual supplies of ±4.5V to ±18V. Key electrical parameters include a maximum on-resistance of 350Ω, input leakage current less than 0.5nA at +25°C, and power consumption under 1.5mW. It supports TTL and CMOS logic compatibility with 0.8V and 2.4V thresholds.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure provides overvoltage protection up to 40V beyond supply rails during power-up, power-down, and fault conditions.
• Guaranteed break-before-make operation prevents simultaneous connection of multiple inputs to the output.
• All switches turn off when power supplies are removed, ensuring signal isolation during power loss.
• Output clamps at approximately 1.5V below supply rails to protect sensitive downstream circuit components.

• Signal Routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE+' against official documentation to confirm the plastic DIP package and commercial temperature range (0°C to +70°C). Ensure the ordering information matches the required pin count and channel configuration for your design. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential obsolescence notices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault protection is required for analog signals exceeding standard supply limits. The 350Ω on-resistance and low leakage make it suitable for precision applications. Verify that the 16-pin DIP package fits the PCB layout constraints. Consider the MAX355 if a dual 4-channel configuration is needed instead of the single 8-channel topology provided by the MAX354.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX354 belongs to the Maxim Integrated fault-protected multiplexer family, designed to safeguard analog circuits from overvoltage events. It serves as an improved second source for legacy parts like the MAX358/MAX359 and is pin-compatible with ADI's ADG508F/ADG509F series. This lineage ensures reliability in industrial environments where transient voltage spikes are common.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include the MAX358, MAX359, DG458, DG459, ADG508F, and ADG509F due to pin compatibility and similar functional characteristics. Verify electrical specifications such as on-resistance and leakage currents match the original design requirements before substitution.
