MAX4537ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537ESE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with a common enable pin. It features four normally closed (NC) switches and operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The 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 with off-leakage current of 1nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The device is housed in a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature grade. The 'E' suffix indicates the extended industrial temperature range (-40°C to +85°C), while the 'S' suffix denotes the narrow SOIC package. Confirm that the component meets RoHS requirements if applicable to your manufacturing standards. Always cross-reference the manufacturer's latest datasheet for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4537ESE when normally closed (NC) switch configuration is required for the application design. Ensure the supply voltage range aligns with the system's power architecture, as the device supports both single and dual supplies. Verify that the 200Ω maximum on-resistance meets the signal integrity requirements. Consider the 16-pin Narrow SO package constraints regarding PCB layout and thermal dissipation capabilities during the initial circuit design phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4537ESE belongs to the MAX4536/MAX4537/MAX4538 family of quad SPST analog switches. While the MAX4536 provides normally open switches and the MAX4538 offers a mixed configuration, the MAX4537 specifically provides four normally closed switches. All three variants share identical pinouts, electrical characteristics, and packaging options, allowing for flexible design choices based on the default state requirements of the analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536ESE and MAX4538ESE are pin-compatible alternatives within the same series. The MAX4536ESE provides normally open switches, whereas the MAX4538ESE combines two normally open and two normally closed switches. These parts can replace the MAX4537ESE if the default switch state does not impact the circuit functionality or if external pull-up/pull-down resistors can compensate for the logical difference.
