MAX381CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX381CPE is a precision, low-voltage analog switch fabricated with Maxim’s silicon-gate process. It features a single-pole single-throw (SPST) normally open configuration in a 16-pin Plastic DIP package. The device operates on a single positive supply (+3V to +15V) or split supplies (±3V to ±8V). Electrical characteristics include an on-resistance of 20Ω typical and 35Ω maximum, with guaranteed matching within 2Ω between channels. Turn-on time is typically 175ns and turn-off time is 60ns. Power consumption is less than 10µW, and charge injection is guaranteed below 5pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPE indicates the standard plastic DIP package and commercial temperature range. Confirm RoHS compliance status as original datasheets may predate modern directives. Ensure pinout compatibility with existing PCB layouts before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low voltage operation and high accuracy. Verify that the required analog signal range fits within the specified supply rails. Consider thermal derating if operating near the upper temperature limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX381/MAX383/MAX385 family of precision analog switches. The MAX381 specifically provides a single SPST switch, while other variants offer different configurations like DPST or SPDT. All share similar electrical performance metrics and fabrication processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include DG401, DG403, and DG405. Verify that substitute parts meet the specific on-resistance flatness and leakage current requirements of the original design.
