MAX355EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX355EPE+ is a dual 4-channel fault-protected analog multiplexer in a 16-pin Plastic DIP package. It operates from a single 4.5V to 36V supply or ±4.5V to ±18V dual supplies. The device features a maximum on-resistance of 350Ω and input leakage current less than 0.5nA at +25°C. Digital inputs support TTL and CMOS logic without pull-up resistors, with thresholds of 0.8V and 2.4V. Break-before-make operation is guaranteed, and power consumption is under 1.5mW.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure protects against overvoltage up to 40V beyond supply rails during power-up, power-down, and fault conditions.
• All switches turn off when supplies are off, and the on switch turns off during overvoltage events.
• Output clamps at 1.5V below supply rails to protect sensitive circuit components.
• TTL and CMOS logic compatibility ensures reliable operation without external pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the exact part number MAX355EPE+. Confirm the suffix indicates the extended temperature range (-40°C to +85°C) and the 16-pin Plastic DIP package. Ensure documentation aligns with Analog Devices specifications for this specific variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX355EPE+ for applications requiring dual 4:1 multiplexing with robust fault protection. Consider the 350Ω on-resistance and low leakage characteristics for signal integrity. Verify that the operating voltage range fits within the specified single or dual supply limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX355EPE+ belongs to the MAX354/MAX355 family of fault-protected analog multiplexers. It serves as a dual-channel version of the single 8-channel MAX354. Both devices share identical protection circuitry and electrical characteristics, differing primarily in channel count and configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX355EPE+ is pin-compatible with the ADG509F. It also serves as an improved second source for the MAX359 and DG459. Verify pinout and electrical parameters before substituting with these alternatives.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX355EPE+ handle overvoltage conditions?

It uses a series FET protection scheme that limits input current to sub-microamp levels and clamps the output at approximately 1.5V below the supply rails, protecting against continuous input voltages up to ±40V.

What is the break-before-make interval?

The device guarantees a break-before-make interval of up to 100ns, which prevents input-to-input shorts during switching transitions.

Can the MAX355EPE+ operate with a single supply?

Yes, it can operate from a single +4.5V to +30V supply by connecting the V- pin to ground (0V).
