MAX394CAP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CAP+T is a low-voltage, quad single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. 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 at ±4.5V and guarantees matching within 2Ω between channels. It offers break-before-make switching with turn-off times under 75ns and turn-on times under 130ns. Quiescent current is less than 1μA. Logic inputs are TTL and CMOS compatible. The component is housed in a 20-pin SSOP package and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure that the '+T' designation aligns with reel packaging requirements if applicable. Confirm RoHS compliance status through manufacturer certificates. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage operation with minimal power consumption. Verify that the required analog signal range fits within the specified supply voltage limits. Consider the thermal performance characteristics if operating near the upper temperature boundary. Ensure logic input levels match the system's control voltage standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX394 family of precision analog switches. It serves as a direct replacement for older models like the MAX333 and MAX333A due to its pin-compatible design. The component utilizes Maxim’s low-voltage silicon-gate process technology to achieve improved performance metrics compared to legacy discrete solutions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394CAP+T is explicitly documented as pin-compatible with the MAX333 and MAX333A. Designers replacing these legacy components should verify that the new switch meets the specific on-resistance and leakage requirements of the original circuit design.
