MAX394CPP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CPP+ 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 at ±4.5V and guaranteed matching within 2Ω between channels. It provides break-before-make switching with turn-off times under 75ns and turn-on times under 130ns. Quiescent current is less than 1μA. Logic inputs are TTL and CMOS compatible. The component is housed in a 20-pin Plastic DIP package and supports a commercial temperature range of 0°C to +70°C.
