ISL54302: 12V, 1.5Ω Quad SPST Switch with Latched Parallel Interface

The ISL54302 is a quad analog bidirectional switch device targeted at industrial applications, including test and measurement equipment. It features low resistance and low leakage along with 12V operation and can be digitally controlled via a latched parallel interface. This parallel interface features a latch input pin that can be used to connect multiple devices into a parallel arrangement.

The ISL54302 can operate from a single, or split bipolar power supply and has a 3V logic interface. The ISL54302 is specified for use over the -40°C to +85°C temperature range and is available in a 20 Ld 4x4 QFN Pb-free package.
