MAX4559CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4559CSE+T is a dual 4-to-1 multiplexer analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It operates on single supplies from +2V to +12V or dual supplies of ±2V to ±6V, supporting rail-to-rail analog signals. The device features ±15kV ESD protection and TTL/CMOS-compatible digital inputs. Key electrical parameters include an on-resistance of 160Ω (±5V supply) or 220Ω (+5V supply), off-leakage current of 1nA at +25°C, and turn-on/turn-off times of 150ns/120ns respectively. It is housed in a 16-pin Narrow SO package with an operating 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 grade. Ensure the component matches the required voltage and leakage specifications for the target application. Cross-reference the manufacturer's part number with authorized distributor listings to confirm authenticity and availability status before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-to-1 multiplexing function is required within a low-voltage system. Consider the 160Ω on-resistance and 1nA leakage characteristics for precision signal paths. Verify that the 0°C to +70°C commercial temperature range meets environmental requirements. Ensure the 16-pin Narrow SO footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. While sharing similar ESD protection and logic interface features, the MAX4559 specifically provides two independent 4-to-1 multiplexers. It differs from the MAX4558 (single 8-to-1 mux) and MAX4560 (triple SPDT switch) in channel configuration and pin assignment.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible alternatives include industry-standard 74HC4051/74HC4052/74HC4053 devices, though these lack the integrated ESD protection and rail-to-rail capabilities. Direct functional replacements within the same family are the MAX4558CSE+T and MAX4560CSE+T, subject to multiplexer versus switch topology requirements.
