MAX4559EEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4559EEE+ is a low-voltage, CMOS analog multiplexer IC configured as a dual 4-to-1 multiplexer. It operates continuously from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. The device features ±15kV ESD protection on all pins without latchup. Key electrical parameters include an on-resistance (RON) of 160Ω at ±5V and 220Ω at +5V, with a channel-to-channel match of 2Ω typical. Off-leakage current is 1nA max at +25°C and 10nA max at +85°C. Switching times are 150ns turn-on and 120ns turn-off at ±5V. It utilizes TTL/CMOS-compatible logic thresholds (+0.8V to +2.4V) and is housed in a 16-pin QSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EEE+' corresponds to the -40°C to +85°C temperature range and 16-pin QSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure input voltage levels remain within the specified logic thresholds for reliable operation. Check absolute maximum ratings for continuous current limits to prevent device damage during system integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-to-1 multiplexing function is required in a compact surface-mount package. The low on-resistance and tight matching between channels make it suitable for precision applications. Consider the supply voltage range and leakage current specifications relative to the target operating temperature. Verify that the pinout is compatible with existing PCB layouts or industry-standard alternatives like the 74HC4052 series if pin compatibility is a design constraint.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4559EEE+ belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. This family shares common architectural features including ESD protection and low-power operation. The MAX4559 specifically provides two independent 4-to-1 multiplexers, distinguishing it from the single 8-to-1 MAX4558 and the triple SPDT MAX4560. All variants utilize the same 16-pin footprint options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin-compatibility with industry-standard 74HC4051/74HC4052/74HC4053 devices. However, electrical characteristics such as on-resistance and leakage differ significantly. Direct substitution requires verification of performance margins under specific load conditions.
