MAX394CWP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CWP is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the analog signal range with a maximum variation of 4Ω. It provides break-before-make switching with a typical delay of 10ns, turn-off times under 75ns, and turn-on times under 130ns. Quiescent current is less than 1μA. Logic inputs are compatible with TTL and CMOS standards.
