ISL54302

12V, 1.5

Ω 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.

Table 1 summarizes the performance of this family.
