MAX4544CSA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4544CSA+ is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features a single-pole/double-throw (SPDT) configuration within an 8-pin SO package. The device operates across a commercial temperature range of 0°C to +70°C. Key electrical parameters include a maximum on-resistance (RON) of 60Ω and a maximum RON matching between channels of 2Ω at +5V. Switching speeds are characterized by a maximum turn-on time (tON) of 150ns and a maximum turn-off time (tOFF) of 100ns. Power consumption is low at 5µW, with leakage currents limited to 100pA maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CSA against official documentation to confirm the 8-pin SO package and commercial temperature range. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer's latest ordering information to confirm current production status and availability constraints before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-pole/double-throw analog switch is required within a standard 8-pin surface-mount footprint. It is suitable for applications needing rail-to-rail signal handling on a single supply. Consider alternative packages like SOT23-6 if board space is constrained, as the MAX4544 family offers pin-compatible options in smaller form factors.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 series of low-voltage, single-supply analog switches. While the MAX4541, MAX4542, and MAX4543 offer dual SPST configurations, the MAX4544 specifically provides dual SPDT functionality. The series shares common electrical characteristics such as low on-resistance and fast switching speeds, differing primarily in internal switch topology and available package styles.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4544ESA+ serves as a direct industrial-grade replacement offering an extended temperature range of -40°C to +85°C while maintaining identical pinouts and electrical specifications.
