MAX394EPP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394EPP is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch in a 20-pin Plastic DIP package. 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 +25°C and guaranteed matching within 2Ω between channels. Turn-on time is typically 130ns and turn-off time is typically 75ns. Quiescent current is less than 1μA. Logic inputs are compatible with TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPP' to confirm the -40°C to +85°C temperature range and 20-pin Plastic DIP package configuration. Ensure that the ordering documentation matches the required lead-free status if applicable, as indicated by '+' suffixes in other variants. Confirm availability directly with Analog Devices or authorized distributors, as stock levels fluctuate.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT switch with low voltage operation is required. The E variant ensures extended industrial temperature performance compared to the C variant. Verify that the system power supply falls within the specified ±2.7V to ±8V dual or +2.7V to +15V single supply ranges to maintain optimal on-resistance characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX394 family of low-voltage analog switches manufactured by Analog Devices/Maxim Integrated. It serves as a direct pin-compatible upgrade for older MAX333 and MAX333A designs, offering improved low-voltage performance and lower power consumption while maintaining similar form factors across various package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394EPP is explicitly documented as a pin-compatible replacement for the MAX333 and MAX333A. Designers upgrading from these legacy parts should verify that the new supply voltage requirements align with the MAX394's operational limits.
