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.
