MAX393C/D is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is INTEGRATED CIRCUIT. Review the specifications below when checking this part for your BOM.
The MAX393C/D is a precision, quad, single-pole/single-throw (SPST) analog switch die featuring two normally open and two normally closed switches. It operates from a single +3V to +15V supply or dual ±3.0V to ±8V supplies. Key electrical parameters include a maximum on-resistance of 60Ω at +5V single supply and 35Ω at ±5V dual supply. The device guarantees an on-resistance match between channels of 2Ω and flatness up to 6Ω. Leakage current is limited to 100nA maximum, with power consumption under 1µW. Switching speeds are characterized by turn-on times up to 170ns and turn-off times up to 50ns at +5V.
Verify the specific ordering suffix and temperature grade required for the application. Confirm that the die form factor meets the assembly capabilities of the target manufacturing process. Ensure proper handling protocols are established for bare die components to prevent electrostatic discharge damage during integration.
Select this component when mixed normally open and normally closed switching functionality is required in a compact footprint. Evaluate the on-resistance specifications against the voltage drop requirements of the signal path. Consider the operating temperature range and supply voltage compatibility before finalizing the design.
This part belongs to the MAX391/MAX392/MAX393 family of precision analog switches. While the MAX391 provides four normally closed switches and the MAX392 offers four normally open switches, the MAX393 combines both types. All variants share similar electrical performance metrics regarding speed and leakage.
