MAX4639EGP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4639EGP is a dual SP4T analog multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a single supply voltage range of 1.8V to 5.5V or dual supplies up to ±2.5V. The device features a maximum on-resistance of 3.5 Ohms and a channel-to-channel matching of 100 milliohms. Key electrical parameters include an 85MHz -3dB bandwidth, 18ns maximum turn-on time, and 7ns maximum turn-off time. Charge injection is specified at 13pC, with off-state leakage current capped at 250pA. The component utilizes a 16-pin TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EGP' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required thermal dissipation capabilities for the intended application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual four-to-one multiplexing is required within low-voltage single-supply systems. The 3.5 Ohm on-resistance makes it suitable for precision applications where signal integrity is critical. Consider the 16-TSSOP package constraints regarding PCB real estate and thermal management during the layout phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4638/MAX4639 family of low-voltage CMOS analog switches. While the MAX4638 offers an 8:1 single-channel configuration, the MAX4639 provides two independent 4:1 channels in the same footprint. Both share similar electrical characteristics but differ in internal topology and control logic requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4638EUE+ serves as a functional alternative if a single 8:1 mux is acceptable instead of dual 4:1 channels. Verify control logic compatibility and pinout alignment before substitution.
