MAX4761ETX+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4761ETX+T is an octal single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices/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. The device includes one logic control input (INA) and an active-low enable input (EN). Key electrical parameters include a maximum turn-on time of 140 ns, a maximum turn-off time of 50 ns, and a -3dB bandwidth of 150 MHz. It is housed in a 36-pin TQFN-EP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the required footprint and ensure the lead-free status aligns with environmental compliance requirements. Cross-reference the ordering suffix to guarantee the correct tape-and-reel packaging configuration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple SPDT switches controlled by a single logic line. Ensure the system power supply falls within the specified 1.8V to 5.5V range. Consider the 36-pin TQFN package dimensions for PCB layout constraints and verify that the thermal dissipation capabilities are sufficient for the intended operating environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4760/MAX4761 family of high-bandwidth analog switches. While the MAX4760 variant provides quad DPDT configurations, the MAX4761 offers octal SPDT functionality. Both share similar electrical characteristics but differ in control logic inputs and switch topology, allowing designers to choose based on specific routing complexity and pin count requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4760ETX+T serves as a functional alternative if DPDT switching is acceptable instead of SPDT. Verify that the control logic interface differences between the two variants do not impact the existing circuit design before substitution.
