MAX4051ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051ESE is a low-voltage CMOS analog multiplexer featuring one 8-channel circuit in a 16-pin Narrow SO package. It operates on single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device provides rail-to-rail analog signal handling with an on-resistance of 125Ω at ±5V and 225Ω at +5V. Off-leakage current is typically 1nA at +25°C, while supply current remains below 1µA. Digital inputs are TTL/CMOS compatible, supporting logic thresholds between 0.8V and 2.4V.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4051 handle signals exceeding the supply rails?

Internal reverse ESD-protection diodes clamp any analog signal exceeding V+ or V-. Designers must limit the forward-diode current to the maximum rating to avoid damage.

What is the recommended power-supply sequencing?

Apply V+ first, followed by V-, then logic inputs, and finally the analog signals (NO and COM) to ensure proper operation and protection.

Is the MAX4051 pin-compatible with other logic families?

Yes, it is pin-compatible with industry-standard 74HC4051 devices, allowing for direct upgrades in existing designs.
