MAX4538CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4538CSE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with a common enable pin. It features two normally open and two normally closed switches. The device operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. On-resistance is 200Ω maximum, matched between channels to 4Ω maximum, and flat to 10Ω maximum over the signal range. Each switch handles rail-to-rail analog signals. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The package is 16 Narrow SO.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range of 0°C to +70°C and the 16-pin narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage limits do not exceed absolute maximum ratings during operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed SPST switches is required in a single package. Verify that the 200Ω on-resistance meets system impedance requirements. Check that the 100ns turn-on time fits within the application's timing constraints. Consider the common enable feature for power management strategies.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4536/MAX4537/MAX4538 family of quad low-voltage SPST analog switches. While the MAX4536 contains four normally open switches and the MAX4537 contains four normally closed switches, the MAX4538 provides a hybrid configuration of two normally open and two normally closed switches. All variants share identical pinouts and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536CSE and MAX4537CSE are pin-compatible alternatives within the same family. Designers requiring different switch configurations (all NO or all NC) may substitute these parts without changing the PCB layout. Verify that the specific switch state requirements match the replacement part's internal configuration.
