MAX4618ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4618ESE+ is a high-speed, low-voltage CMOS analog multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated. It contains two independent 4-channel (SP4T) multiplexers in a 16-pin Narrow SO package. The device operates on a single +2V to +5.5V supply and supports rail-to-rail analog signals. Key electrical parameters include a maximum switch on-resistance of 10Ω at +5V supply and 20Ω at +3V supply. Switching times are specified as 15ns turn-on and 10ns turn-off. Off-leakage current is typically 1nA at +25°C. The component features TTL/CMOS logic compatibility, low crosstalk (<-96dB), and high off-isolation (<-93dB).

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low-voltage data-acquisition systems
• Communications circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'SE' denotes the Narrow SOIC package type. Confirm RoHS compliance status via the '+' designation. Ensure the ordering code matches the required pin configuration and thermal performance specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4:1 multiplexing is required within a standard 16-pin footprint. Consider the on-resistance variation across the voltage range if operating below +5V. Verify that the input logic thresholds align with the system's digital control voltages, particularly at lower supply levels where TTL compatibility may shift.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4617/MAX4618/MAX4619 family of high-speed, low-voltage CMOS analog switches. While electrically similar to the legacy 74HC series, it offers superior leakage and switching speed. The MAX4618 specifically provides two 4-channel multiplexers, distinguishing it from the single 8-channel MAX4617 and the triple SPDT MAX4619.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4617 and MAX4619 variants within the same family, provided the channel count meets design requirements. Industry-standard 74HC4051/74HC4052/74HC4053 devices are pin-compatible but differ electrically; verify on-resistance and leakage limits before substitution.
