MAX4543CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543CPA is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features one normally open (NO) and one normally closed (NC) switch, allowing SPDT configuration. Key electrical parameters include a maximum on-resistance of 60Ω at +5V, with a typical value of 33Ω. On-resistance matching between channels is 2Ω max, and flatness is 6Ω max. The device offers low leakage currents of 100pA max and fast switching speeds with turn-on time up to 100ns and turn-off time up to 75ns. Power consumption is under 5µW. It operates within a temperature range of 0°C to +70°C in an 8-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The 'C' indicates commercial grade (0°C to +70°C), while 'E' denotes extended grade (-40°C to +85°C). Ensure the plastic DIP package matches the target PCB footprint. Confirm RoHS compliance status as per current manufacturing revisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed NO/NC dual switch is required for signal routing. Compare against MAX4541 (dual NO) or MAX4542 (dual NC) if the specific contact configuration differs. Verify that the 60Ω on-resistance meets the system's voltage drop requirements. Check if the 0°C to +70°C temperature range is sufficient for the intended environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4543CPA belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. This series provides various configurations including dual SPST and single SPDT options. The MAX4543 specifically combines one NO and one NC switch, offering flexibility for applications requiring complementary switching actions within a single compact package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include MAX4541CPA and MAX4542CPA, though their switch configurations differ. For extended temperature ranges, consider MAX4543EPA. Verify that any replacement maintains the required on-resistance and switching speed specifications.
