MAX4642EUA+TG104

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4642EUA+TG104 is a dual single-pole/single-throw (SPST) CMOS analog switch from the MAX4641/MAX4642/MAX4643 family. It operates on a single supply voltage ranging from +1.8V to +5.5V and features two normally closed (NC) switches. The device guarantees a maximum on-resistance of 4Ω at +5V and 8Ω at +3V, with an on-resistance flatness of 1Ω at +5V. Switching times are typically 18ns for turn-on and 12ns for turn-off. Quiescent power consumption is less than 0.01µW, and leakage currents remain below 0.35nA across the entire operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental certifications required by your project specifications. Ensure the ordering suffix matches the exact package and tape/reel requirements needed for your assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when dual normally closed switching is required within a low-voltage single-supply environment. Compare against MAX4641 for normally open configurations or MAX4643 for mixed NO/NC needs. Evaluate the 4Ω on-resistance against system impedance requirements and ensure the 1.8V minimum supply aligns with available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX464x series of high-speed, low-voltage analog switches manufactured by Analog Devices Inc./Maxim Integrated. The series includes complementary variants offering different contact states while sharing identical electrical characteristics and pinouts. These devices are designed for applications requiring minimal signal distortion and low power usage in portable electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4641EUA provides the same electrical specifications but with normally open contacts instead of normally closed. MAX4643EUA offers a mixed configuration with one normally open and one normally closed switch. Both alternatives maintain identical pinouts and performance metrics suitable for direct functional substitution where contact state differences are acceptable.
