MAX338ETE-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338ETE-T is a monolithic CMOS analog multiplexer featuring eight single-ended channels. It connects one of eight inputs to a common output via a 3-bit binary address. The device supports dual supplies from ±4.5V to ±20V or a single supply from +4.5V to +30V. Maximum on-resistance is 400Ω at +25°C and 500Ω across the full temperature range. Off-leakage current is less than 20pA, with charge injection typically at 1.5pC. Transition time reaches 500ns maximum. It operates within -40°C to +85°C and uses a 16-pin TQFN-EP package.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance value?

The maximum on-resistance is 400Ω at +25°C and increases to 500Ω across the full operating temperature range.

How does the device handle overvoltage conditions?

Signals exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added if proper power-supply sequencing cannot be guaranteed.
