MAX393CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX393CSE is a precision, quad SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels in a 16-SOIC package. The device supports single supply voltages from 3V to 15V and dual supplies from ±3V to ±8V. Key electrical parameters include a maximum on-resistance of 35 ohms, channel-to-channel matching of 300 milliohms, and a maximum charge injection of 2pC. Switching times are specified at 130ns for turn-on and 75ns for turn-off. Leakage current is limited to 100pA, with a crosstalk specification of -85dB at 1MHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against the manufacturer's official part numbering guide to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for the intended deployment environment. Cross-reference the datasheet revision date to validate parameter accuracy before integration into final designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise resistance matching and low charge injection are critical for signal fidelity. Verify that the operating voltage range aligns with the system power rails. Consider the thermal dissipation capabilities within the SOIC package if multiple channels are driven simultaneously under load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX391-MAX393 family of precision CMOS analog switches. The MAX393 variant specifically offers complementary SPST configurations, providing both normally open and normally closed paths within the same integrated circuit. This configuration simplifies design complexity compared to using separate discrete switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX391CSE and MAX392CSE, which share identical pinouts and core electrical specifications but differ in switch configuration (NC vs NO). Verify functional compatibility regarding the specific channel states required by the application circuit.
