MAX4051AEPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051AEPE is a low-voltage, CMOS analog multiplexer featuring eight bidirectional channels in a 16-pin Plastic DIP package. It operates on dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device guarantees an on-resistance of 100Ω with ±5V supplies, channel match of 6Ω, and off-leakage current of 0.1nA at +25°C. Digital inputs are TTL/CMOS compatible, supporting rail-to-rail analog signal handling.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the 'P' suffix corresponds to the 16-pin Plastic DIP package. Ensure the component meets RoHS requirements if applicable, as standard versions may not be compliant. Cross-reference the manufacturer's ordering information to validate availability and exact specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when pin compatibility with 74HC4051 is required alongside guaranteed on-resistance matching and low leakage. Consider the operating voltage range and temperature requirements. Verify that the 100Ω on-resistance and 0.1nA leakage meet system needs. Evaluate the 16-pin PDIP package constraints against board layout requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4051/MAX4052/MAX4053 family of low-voltage CMOS analog switches. The MAX4051 variant specifically provides an 8-channel multiplexer configuration. The 'A' suffix denotes parts fully characterized for on-resistance match, flatness, and low leakage. The 'E' suffix specifies the industrial temperature range extension.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the standard MAX4051CPE or MAX4051EPE. Other manufacturers offer equivalent 8-channel analog multiplexers such as the SN74LV4051A. Verify electrical parameters like on-resistance and leakage before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic threshold compatibility?

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

How does the device handle overvoltage?

Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V-. Signals exceeding these limits will cause diode conduction.

What is the maximum power supply difference?

The sum of V+ and V- cannot exceed the absolute maximum rating of +17V, even if the supplies are not symmetrical.
