MAX4559CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4559CEE is a low-voltage CMOS analog multiplexer configured as a dual 4-to-1 switch. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features ±15kV ESD protection on all pins and handles Rail-to-Rail analog signals. Key electrical parameters include an on-resistance of 220Ω (max) at +5V single supply, 1nA off-leakage current at +25°C, and turn-on/turn-off times of 250ns/150ns (max). It is housed in a 16-pin QSOP package with an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE' indicates the commercial temperature range (0°C to +70°C) and QSOP package. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the design accounts for the absolute maximum ratings regarding continuous power dissipation and voltage limits into any terminal to prevent permanent damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-to-1 multiplexer configuration is required within a 16-pin footprint. It serves as a pin-compatible replacement for industry-standard 74HC4052 devices while offering superior ESD protection and lower leakage currents. Consider the higher on-resistance compared to high-speed switches if signal integrity at high frequencies is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. While the MAX4558 provides an 8-to-1 multiplexer and the MAX4560 offers triple SPDT switches, the MAX4559 specifically provides two independent 4-to-1 channels. All members share identical pinouts and core switching characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin-compatibility with industry-standard 74HC4051/74HC4052/74HC4053 devices. Designers replacing these standard logic switches should verify that the MAX4559's higher on-resistance and different drive requirements meet the system specifications.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ESD protection mechanism function?

The device uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected pins and ground. During an ESD strike, the SCRs turn on to bypass surge current safely to ground.

What are the logic input thresholds?

All digital inputs have +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply or dual ±5V supplies.

Is the MAX4559EEE available in the same package?

Yes, the MAX4559EEE is available in the 16-pin QSOP package but supports an extended industrial temperature range of -40°C to +85°C, whereas the CEE version is limited to 0°C to +70°C.
