MAX4619CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4619CSE+ is a high-speed, low-voltage CMOS analog switch configured as three single-pole/double-throw (SPDT) units in a 16-pin Narrow SO package. It operates on a +2V to +5.5V single supply and handles rail-to-rail analog signals. Key electrical parameters include a maximum on-resistance of 10Ω at +5V and 20Ω at +3V, with a guaranteed 1Ω match between channels. Switching times are 15ns for turn-on and 10ns for turn-off. Off-leakage current is limited to 1nA at +25°C. The device features TTL/CMOS-compatible digital inputs, off-isolation exceeding -93dB, crosstalk below -96dB, and total harmonic distortion under 0.017%.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against official documentation to confirm the commercial temperature range and lead-free status. Ensure the narrow SOIC footprint matches the target PCB land pattern. Confirm that the single-supply logic thresholds align with the host microcontroller's output levels at the intended operating voltage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when three independent SPDT switching paths are required within a compact surface-mount form factor. The MAX4619 offers lower on-resistance compared to standard 74HC series alternatives while maintaining identical pinouts. Consider the 10ns turn-off time for applications requiring rapid signal path reconfiguration without cross-talk interference.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4619 belongs to the MAX4617/MAX4618/MAX4619 family of high-speed CMOS analog multiplexers and switches manufactured by Analog Devices Inc./Maxim Integrated. This series provides pin-compatible options for 8:1 multiplexing, dual 4:1 multiplexing, and triple SPDT switching configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4619 handle overvoltage conditions on analog pins?

Internal reverse ESD-protection diodes clamp voltages exceeding VCC or GND. Designers must limit forward-diode current to the maximum rating or add external blocking diodes if power sequencing cannot be controlled.

What is the behavior of the OFF-state capacitance at high frequencies?

The OFF-state switch acts like a capacitor, passing higher frequencies with less attenuation. In 50Ω systems, off-isolation degrades significantly above 20MHz, dropping approximately 20dB per decade.

Are the input and output pins interchangeable?

Yes, the X, Y, and Z pins are bidirectional. Either side of a given switch can function as an input or output, allowing signals to pass equally well in both directions.
