MAX4621CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4621CPE+ is a dual, high-speed analog switch in a 16-pin Plastic DIP package. It features two single-pole/single-throw (SPST) normally open channels with a maximum on-resistance of 5Ω and guaranteed matching within 0.5Ω. The device operates from a single supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, and off-leakage current less than 5nA at +85°C. It supports continuous currents up to 100mA and functions within a commercial temperature range of 0°C to +70°C.

• Fast switching speeds with break-before-make operation available in the pin-compatible MAX4622 variant

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing and data-acquisition systems
• Military radios and communication systems
• PBX and PABX telephone switching networks

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C), distinct from the 'E' suffix which covers -40°C to +85°C. Confirm the 'PE' designation corresponds to the 16-lead plastic DIP package. Ensure the component is sourced as lead-free ('+') compliant. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching is required with low distortion and high linearity. The MAX4621 is suitable for applications needing rail-to-rail signal swing without external level shifting. Consider the MAX4622 if break-before-make timing is critical to prevent signal overlap. Verify that the 5Ω on-resistance meets the voltage drop requirements for the target load current within the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX462x family of precision analog switches manufactured by Analog Devices/Maxim Integrated. It serves as a direct pin-compatible replacement for legacy DG401 devices, offering improved performance metrics such as lower leakage and faster switching times while maintaining similar form factors. The family includes complementary configurations like the SPDT MAX4622 and DPST MAX4623.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4621CPE+ is explicitly documented as a pin-compatible replacement for the DG401CPE+. Designers upgrading from older discrete solutions or legacy ICs should verify that the new switching characteristics align with the system's timing and isolation requirements.
