MAX394CAP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CAP+T is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the analog signal range with a maximum variation of 4Ω. It offers break-before-make switching with a typical delay of 10ns, turn-off times under 75ns, and turn-on times under 130ns. Quiescent current is less than 1μA. Logic inputs are TTL and CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CAP+' indicates the commercial temperature range and SSOP package. Confirm RoHS compliance status through official documentation as indicated by the '+' suffix. Ensure the ordering code matches the required tape-and-reel quantity if applicable for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation and rail-to-rail signal handling are required. Verify that the supply voltage range meets the application needs, considering both single and dual supply configurations. Check logic level compatibility to ensure proper interface with the controlling digital circuitry without additional level shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX394 is part of Maxim Integrated's low-voltage analog switch family. It replaces older models like the MAX333 and MAX333A while offering improved performance in low-power applications. The device utilizes a silicon-gate process to achieve low charge injection and high electrostatic discharge protection.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394 is pin-compatible with the MAX333 and MAX333A. Designers upgrading from these legacy parts should verify that the new on-resistance and leakage specifications meet the system requirements.
