MAX354CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354CPE is a fault-protected analog multiplexer featuring a single 8-channel (1x8) configuration housed in a 16-pin Plastic DIP package. It operates from a single supply of 4.5V to 36V or dual supplies of ±4.5V to ±18V. The device provides overvoltage protection up to 40V beyond the supply rails during power-up, power-down, and fault conditions. Key electrical parameters include a maximum on-resistance of 350Ω, an input leakage current of less than 0.5nA at +25°C, and a break-before-make interval of up to 100ns. The component supports TTL and CMOS logic compatibility without pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure protects against overvoltage up to 40V beyond supply rails.
• Guaranteed break-before-make operation prevents simultaneous connection of multiple inputs.
• All switches turn off automatically when power supplies are removed.
• Compatible with standard TTL and CMOS logic levels without requiring external pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Plastic DIP package format. Confirm that the ordering code matches the manufacturer's current naming convention for this legacy part number. Ensure the intended application environment remains within the specified operating temperature limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX354CPE when a single 8-channel multiplexer with high-voltage fault protection is required. This model is suitable for applications needing operation from a single supply up to 36V or dual supplies up to ±18V. Consider the 350Ω on-resistance and low leakage characteristics for signal integrity requirements. Verify that the 16-pin DIP package fits the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX354CPE belongs to the MAX354/MAX355 family of fault-protected analog multiplexers manufactured by Analog Devices / Maxim Integrated. The MAX354 variant specifically provides an 8-channel configuration, whereas the MAX355 offers a dual 4-channel setup. Both share identical fault-protection circuitry and pinout architectures, differing primarily in channel count and internal decoder logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the MAX354 as an improved second source for the MAX358 and MAX359. It is also noted as being pin-compatible with the ADG508F and ADG509F. Verify functional equivalence and parameter alignment before substituting these specific part numbers.
