MAX4674EEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4674EEE+T is a low-voltage CMOS analog switch containing four independent 2:1 multiplexers/demultiplexers. It operates from a single +1.8V to +5.5V supply and features a maximum on-resistance of 4Ω at +5V and 6Ω at +3V. The device guarantees a channel-to-channel on-resistance match of 0.4Ω max and flatness of 0.8Ω max over the signal range. Switching speeds include turn-on times up to 18ns and turn-off times up to 6ns at +5V. Off-leakage current is limited to 0.5nA max at +25°C. Digital inputs are TTL/CMOS compatible, with logic thresholds ensuring compatibility across the operating voltage range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package code 'E' corresponds to the 16-pin QSOP format required for your design. Confirm that the temperature range covers -40°C to +85°C for your application environment. Ensure power sequencing places V+ before logic inputs to prevent latch-up or excessive leakage currents during startup conditions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad 2:1 multiplexer configuration is necessary within a single package footprint. Consider the 4Ω on-resistance limit at +5V and 6Ω at +3V to ensure signal integrity meets system requirements. Verify that the 16-pin QSOP package dimensions fit the available PCB space and that the thermal dissipation characteristics are adequate for the expected load currents.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4674EEE+T belongs to the Maxim Integrated MAX4674 family of low-voltage analog switches. This series provides multiple packaging options including QFN, TSSOP, SO, and QSOP to accommodate various board layout constraints. The device represents a standard solution for signal routing in mixed-signal environments requiring low distortion and high isolation between channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives within the same family include the MAX4674EUE (TSSOP-16) and MAX4674ESE (Narrow SOIC-16). These parts share identical electrical specifications but differ only in the physical package outline. Verify that the substitute package fits the existing footprint or allows for re-layout without changing trace impedances.
