MAX4537CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537CPE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch featuring four normally closed (NC) switches and a common enable pin. It operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The device provides rail-to-rail signal handling with an on-resistance of 200Ω maximum, matched between channels to 4Ω maximum and flat to 10Ω maximum over the specified signal range. Off-leakage current is limited to 1nA at +25°C and 10nA at +85°C. Digital inputs utilize 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The component is housed in a 16-PDIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'C' confirms the commercial temperature range of 0°C to +70°C and the Plastic DIP (PDIP) package configuration. Ensure the manufacturer designation matches Analog Devices Inc./Maxim Integrated specifications. Confirm RoHS compliance status as indicated in the official documentation before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST configuration is required for low-voltage applications. Verify that the supply voltage range (+2V to +12V) aligns with system power constraints. Consider the 200Ω maximum on-resistance and 1nA off-leakage characteristics against signal integrity requirements. Ensure the 16-PDIP package fits the available PCB footprint.

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 features normally open switches and the MAX4538 combines both types, the MAX4537 specifically provides four normally closed switches. All variants share identical pinouts and electrical characteristics except for the switch state logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4536CPE and MAX4538CPE are pin-compatible alternatives within the same series. Designers must account for the difference in switch states: MAX4536 uses normally open contacts, while MAX4538 utilizes a mixed configuration of two normally open and two normally closed switches.
