MAX4656ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4656ESA+ is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 10 Ω at ±15V supplies and supports continuous currents up to 300mA with peak currents reaching 400mA. The device operates within a supply voltage range of +9V to +40V for single-supply or ±4.5V to ±20V for dual-supply configurations. Key electrical parameters include a turn-on time of 200ns, turn-off time of 100ns, off-leakage current of 10nA, and charge injection of 23pC. It is housed in an 8-pin SO package and functions over a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and thermal characteristics. Ensure that the operating environment remains within the specified temperature limits and that supply voltages do not exceed absolute maximum ratings. Check for RoHS compliance status if required by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous current switching is required alongside low on-resistance. Consider the 8-pin SO package constraints for thermal dissipation. Verify that the logic levels match the system's TTL/CMOS standards and ensure adequate heat sinking if operating near maximum power dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4655–MAX4658 family of medium-voltage CMOS analog switches. While the MAX4655 and MAX4657 are normally closed variants, the MAX4656 and MAX4658 are normally open. The MAX4656ESA+ specifically denotes the normally open configuration in an 8-pin SO package with industrial temperature rating.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG417 and DG418 are listed as pin-compatible alternatives. Verify that substitute components meet the specific current handling requirements and on-resistance specifications before implementation.
