ISL54302
FN6592.0
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.
Table 1 summarizes the performance of this family.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.

NOTES:
4. Flatness is defined as the delta between the maximum and minimum rON values over the specified voltage range.
5. Between any two switches.
6. CS_LATCH must remain low when changing SW-CTRL(1-4) condition. Likewise, while CS_LATCH is being toggled, it is important to keep SW-
CTRL(1-4) in the intended switch condition.
7. Typical Values are not production tested
8. Digital Characteristics remain stable with respect to VPLUS and VSS variation. These parameters are controlled by the difference between VSS
and VDD, which the user should maintain at a constant spread of VDD = VSS + 3V.
9. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
10. Limits established by characterization and are not production tested.
