MAX4509CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4509CSE+T is a dual 4-to-1 fault-protected multiplexer housed in a 16-pin Narrow SO package. It operates with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. The device provides ±40V overvoltage protection when power is off and ±25V protection when supplies are active. Key electrical parameters include a maximum on-resistance of 400Ω, an on-resistance match between channels of 15Ω max, and a fault-response time of 20ns. Logic inputs are TTL/CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging by consulting the manufacturer's official documentation. Confirm the 'C' suffix corresponds to the commercial temperature range of 0°C to +70°C. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability for industrial applications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for designs requiring high-voltage fault protection without power sequencing. Verify that the dual 4-to-1 configuration meets channel requirements compared to the single 8-to-1 alternative. Ensure the logic thresholds align with the system's digital control levels under the intended supply voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4508/MAX4509 family of fault-protected multiplexers. It serves as a pin-compatible replacement for industry-standard DG508/DG509 devices while offering enhanced overvoltage protection and rail-to-rail signal handling capabilities for high-voltage analog switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4508 is the single-channel equivalent within the same family. Direct pin-compatible replacements include the DG509. Verify functional compatibility before substituting with other fault-protected multiplexers.
