MAX4537CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4537CEE 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 device offers an on-resistance of 200Ω max, matched between channels to 4Ω max, with flatness of 10Ω max over the signal range. It handles rail-to-rail analog signals with off-leakage current of 1nA at +25°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The component is housed in a 16-pin QSOP package and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CEE' to confirm the 16-pin QSOP package and commercial temperature range (0°C to +70°C). Ensure the design requires normally closed (NC) contacts, as this variant differs electrically from the MAX4536 (NO) and MAX4538 (mixed NO/NC). Confirm that the supply voltage limits and logic thresholds align with the system requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4537CEE when a quad SPST switch with normally closed contacts is required. Verify that the application supports the specified on-resistance and leakage characteristics. Consider the 16-pin QSOP package constraints for board layout. Ensure the operating environment remains within the 0°C to +70°C temperature range defined by the 'C' suffix.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4537CEE belongs to the MAX4536/MAX4537/MAX4538 family of quad, low-voltage SPST analog switches. These devices are designed as pin-compatible replacements for the 74HC4316. The MAX4537 specifically provides four normally closed switches, distinguishing it from the MAX4536's normally open configuration and the MAX4538's mixed configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4537CEE is pin-compatible with the MAX4536CEE and MAX4538CEE. When replacing the MAX4536, verify that the circuit tolerates the normally closed state. When replacing the MAX4538, ensure the mixed NO/NC configuration is not required.
