MAX383CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX383CSE is a precision, low-voltage analog switch featuring two SPDT poles with normally open and normally closed contacts. It operates on a single positive supply (+3V to +15V) or split supplies (±3V to ±8V). The device offers an on-resistance of less than 35 Ω, guaranteed to match within 2 Ω between channels and remain flat over the specified analog signal range. Key electrical parameters include a turn-on time of less than 175 ns, a turn-off time of less than 100 ns, and charge injection of less than 5 pC. Off-channel leakage is less than 250 pA at +25°C and less than 2.5 nA at +85°C. It utilizes CMOS-logic inputs for reduced loading and is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the 0°C to +70°C temperature range and 16-pin Narrow SOIC package. Confirm that the ordering information matches the manufacturer's current documentation, as legacy part numbers may have updated specifications or alternative packaging options available from Analog Devices/Maxim Integrated.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required with low voltage operation. Ensure the application stays within the specified analog signal range to maintain resistance flatness. Verify logic level compatibility with the system's control voltage, as the device supports TTL/CMOS inputs across multiple supply configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX383CSE belongs to the MAX381/MAX383/MAX385 family of precision, low-voltage analog switches manufactured by Maxim Integrated, now part of Analog Devices.
