MAX4638EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4638EUE+ is a single-channel, 8-to-1 CMOS analog multiplexer housed in a 16-pin TSSOP package. It operates from a single +1.8V to +5.5V supply or dual ±2.5V supplies. Key electrical parameters include a maximum on-resistance of 3.5Ω at +5V and 6Ω at +3V, with an on-resistance match between channels of 0.4Ω. The device features a -3dB bandwidth of 50MHz, transition times of 18ns (Ton) and 7ns (Toff), and a maximum leakage current of 0.25nA at +25°C. It supports bidirectional signal handling and includes TTL/CMOS-compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUE+' corresponds to the 16-pin TSSOP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering quantity matches the manufacturer's standard packaging configuration for this specific part number variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4638EUE+ when a single 8:1 multiplexing function is required within a compact surface-mount footprint. Consider this component for applications demanding low on-resistance and high off-isolation under low-voltage conditions. Verify that the system's logic levels align with the specified VIH and VIL thresholds for reliable switching performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4638/MAX4639 family of low-voltage analog multiplexers manufactured by Analog Devices / Maxim Integrated. The MAX4638 variant specifically provides a single 8:1 configuration, whereas the MAX4639 offers a dual 4:1 setup. Both share similar electrical characteristics and are designed for portable and battery-powered instrumentation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX4638 series such as MAX4638ESE+ (SOIC package) or MAX4638ETE+T (TQFN package), provided the pinout and package dimensions are compatible with the existing design constraints.
