MAX4638ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4638ETE+T is a single-channel, 8-to-1 CMOS analog multiplexer housed in a 16-pin TQFN package with an exposed pad. 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 a typical bandwidth of 50MHz for the MAX4638 variant. The device features a transition time of up to 20ns, off-leakage current of 0.35nA, and low supply current of 1µA. It supports bidirectional signal flow and TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports single-supply operation from 1.8V to 5.5V or dual ±2.5V supplies
• Features guaranteed low on-resistance (3.5Ω) and high bandwidth (up to 85MHz)
• Provides break-before-make switching to prevent signal overlap
• Includes an enable input for simplified cascading and power management

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic Test Equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Ensure the exposed pad connection requirements are met during PCB layout to maintain thermal performance and electrical grounding specifications as defined in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8:1 mux configuration is required within a compact surface-mount footprint. Consider the MAX4639 if a dual 4:1 topology is needed instead. Verify that the system voltage range aligns with the specified 1.8V to 5.5V operational limits and that the 3.5Ω on-resistance meets the signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4638/MAX4639 family of low-voltage analog multiplexers manufactured by Analog Devices / Maxim Integrated. The ETE+ suffix specifically denotes the 16-pin TQFN-EP package variant with lead-free/RoHS-compliant construction and an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives within the same series include the MAX4638EUE+T (16-TSSOP) and MAX4638ESE+T (16-SO). For dual-channel applications, the MAX4639ETE+T offers a 4:1 dual mux configuration in the same package.
