MAX4618CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4618CSE is a high-speed, low-voltage CMOS analog switch configured as two independent 4:1 multiplexers in a 16-pin Narrow SO package. It operates on a single +2V to +5.5V supply and supports rail-to-rail analog signals. Key electrical parameters include a maximum on-resistance of 10Ω at +5V and 20Ω at +3V, with a channel-to-channel match of 1Ω max. Switching times are 15ns for turn-on and 10ns for turn-off. The device features low off-leakage current (1nA max at +25°C), charge injection of 3pC, and crosstalk below -96dB.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' against the manufacturer's ordering information to confirm the package type and temperature range. Ensure that any alternative part numbers selected maintain compatibility with the required voltage levels and switching speeds for the intended application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel multiplexing is required within a compact surface-mount footprint. Consider the on-resistance variation across different supply voltages (+3V vs +5V) and operating temperatures. Verify that the logic thresholds align with the system's digital control voltage levels to ensure reliable switching performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4617/MAX4618/MAX4619 family of high-speed, low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4618 specifically provides two 4-channel multiplexer sections, distinguishing it from the 8-channel MAX4617 and the SPDT switch configuration of the MAX4619.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4618CSE+ is the lead-free/RoHS-compliant version of this component. Other pin-compatible options within the same family include the MAX4617 and MAX4619, though their channel configurations differ.
