MAX4761ETX+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4761ETX+ is an octal single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features eight low-capacitance switches with a typical on-resistance of 2.0 Ω and a maximum of 3.5 Ω at V+ = 2.7V. The device provides a -3dB bandwidth of 150 MHz, off-isolation of 80 dB, and crosstalk of 95 dB at 100 kHz. It includes one logic control input (INA) and an active-low enable input (EN). Packaged in a 36-pin TQFN (6mm x 6mm) with an exposed pad, it supports rail-to-rail signal handling and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Octal SPDT configuration with dedicated enable input for high-impedance state control
• Low on-resistance with tight channel-to-channel matching for minimal signal distortion
• High-speed data switching capability with sub-nanosecond skew and low charge injection

Analog Switches, Multiplexers, Demultiplexers Applications

• USB 1.1 and USB 2.0 (Full Speed 12Mbps) signal-switching compliant systems
• Data and audio signal routing in portable devices
• Cellular phones and PDAs/handheld devices
• Notebook computers requiring compact signal multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the package type matches the 36-pin TQFN specification and ensure the lead-free/RoHS-compliant status aligns with project requirements. Cross-reference the ordering suffix 'T' for tape-and-reel packaging if applicable to assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an octal SPDT topology is required rather than quad DPDT configurations found in the MAX4760 family. Ensure the system logic levels are compatible with the IN_ and EN inputs, which accept up to +5.5V regardless of the supply voltage. Consider the 36-pin TQFN footprint constraints and thermal dissipation requirements associated with the exposed pad design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4760/MAX4761 series of high-bandwidth analog switches. While the MAX4760 offers a quad DPDT architecture controlled by four logic inputs, the MAX4761 provides an octal SPDT arrangement managed by a single INA input and an EN pin. Both variants share similar electrical characteristics regarding on-resistance, bandwidth, and power supply ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4761AETX+ serves as a functional alternative within the same series, offering identical specifications but featuring lower 1.8V logic thresholds for improved compatibility with low-voltage digital interfaces.
