MAX393CUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX393CUE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates four independent 1:1 switches in a 16-TSSOP package. The device operates with a single supply voltage ranging from 3V to 15V or dual supplies of ±3V to ±8V. Key electrical specifications include a maximum on-resistance of 35 ohms and a channel-to-channel matching of 300 milliohms. Switching times are specified at a maximum of 130ns for turn-on and 75ns for turn-off. The component exhibits low charge injection of 2pC and off-state leakage current of 100pA maximum. It provides -85dB crosstalk at 1MHz and functions within a commercial temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUE' against the manufacturer's official part numbering guide to confirm the package type, temperature grade, and lead-free status. Ensure compatibility with the 16-TSSOP footprint during PCB layout. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference with the latest datasheet revision to ensure all electrical parameters meet design requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX393CUE when a quad SPST configuration is required with moderate on-resistance and low cost. Compare against the MAX313 series if lower on-resistance is needed, noting the higher voltage requirements. Consider the MAX393EUE variant if an extended industrial temperature range (-40°C to 85°C) is necessary instead of the commercial grade offered by the C suffix. Evaluate switching speed and leakage current requirements against other members of the MAX391-393 family.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX393 belongs to the MAX391-MAX393 family of quad SPST analog switches from Maxim Integrated, now part of Analog Devices. These devices are designed for general-purpose signal switching applications. The family shares similar pinouts and control logic but varies in on-resistance, voltage range, and temperature grades. The MAX393 specifically targets applications requiring balanced performance between speed, leakage, and cost in a standard TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX393EUE+T is a verified alternative offering identical electrical characteristics but with an extended industrial temperature range (-40°C to 85°C). Verify that the E suffix meets thermal requirements if operating conditions exceed the commercial range of the C suffix. Both parts share the same 16-TSSOP package and pinout.
