MAX4737ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4737ETE+T is a quad single-pole single-throw (SPST) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a maximum on-resistance of 3 Ohms. The device supports a continuous DC switch current of 100 mA, with a maximum power dissipation of 500 mW. Key switching parameters include a maximum turn-on time of 80 ns and a maximum turn-off time of 40 ns. It functions within an ambient temperature range of -40°C to +85°C and is housed in a TQFN-EP-16 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ETE against official datasheets to confirm the TQFN-EP-16 packaging and tape-and-reel shipping configuration. Ensure compatibility with RoHS directives and check for lead-free status if required by assembly standards. Confirm availability through authorized distributors as stock levels fluctuate.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with low on-resistance and fast switching speeds. Compare against other members of the MAX4737 family for alternative pinouts or package types such as TSSOP or UCSP. Validate that the 100 mA continuous current rating meets the load requirements of the target application circuit.
