MAX4743EKA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4743EKA+T is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.6V to +3.6V supply and features low on-resistance of 0.8Ω max at +3V. The device includes one normally open (NO) and one normally closed (NC) channel, with fast switching speeds of tON = 24ns and tOFF = 16ns max. It consumes less than 1µW of quiescent power and handles rail-to-rail analog signals. The component is housed in an 8-pin SOT-23 package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EKA' corresponds to the 8-pin SOT-23 package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging as specified in the manufacturer's documentation. Ensure compatibility with the required voltage levels and signal routing requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST switch with mixed NO/NC functionality is required. It is suitable for applications needing low on-resistance and fast switching within a low-voltage single-supply environment. Consider the SOT-23 package size for space-constrained designs requiring break-before-make timing characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4743EKA+T belongs to the MAX4741/MAX4742/MAX4743 family of low-voltage analog switches. While the MAX4741 offers two NO switches and the MAX4742 provides two NC switches, the MAX4743 uniquely combines one NO and one NC channel. All variants share similar electrical characteristics and package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4741EKA+T: Replaces if only normally open switches are needed. MAX4742EKA+T: Replaces if only normally closed switches are needed. Both maintain identical pinouts and electrical specifications except for the switch configuration.
