MAX4736ELB+ is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is SPDT, 2 FUNC, 1 CHANNEL, CMOS. Review the specifications below when checking this part for your BOM.
The MAX4736ELB+ is a single, low-voltage analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 5.5V and features a maximum on-resistance of 500mΩ. The device utilizes a 10-µDFN (2x2) surface-mount package and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a channel-to-channel matching of 3mΩ, off-state leakage current of 100nA, and a turn-on time of 630ms. The component is RoHS compliant and classified as obsolete.
This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Buyers must confirm the specific lot date code and physical condition before acquisition, as no new production units are available directly from the source.
Designers should evaluate the 630ms turn-on time against system timing requirements, as this value is significantly higher than modern high-speed switches. The 500mΩ on-resistance may introduce insertion loss in sensitive analog paths. Ensure the 10-µDFN footprint matches the PCB layout constraints and thermal dissipation capabilities of the target application environment.
The MAX4736 belongs to the Maxim Integrated family of low-voltage analog switches. It shares functional similarities with other devices in the series but is distinguished by its specific pinout and package dimensions. As part of the broader portfolio, it serves as a legacy solution for compact, low-power switching applications where space is limited.
Publicly confirmed substitute part numbers are not provided in the available documentation. Engineers should consult the manufacturer's official obsolescence notices or cross-reference guides for recommended alternatives that match the required electrical parameters and package type.
