FN6461.0
Ultra Low ON-Resistance, Low Voltage,
Single Supply, Single SPST/1:2
Distribution Analog Switch
The Intersil ISL54054 and ISL54055 devices consist of low
ON-resistance, low voltage, bi-directional SPST analog
switches designed to operate from a single +1.8V to +5.5V
supply. These devices have an unique architecture. They
have two signal pins (pin 1 and pin 3) that are
simultaneously connected or disconnected to a common pin
(pin 4) under the control of a single logic control pin (pin 6).
The ISL54054 switches are OFF when the logic is low and
ON when the logic is high. The ISL54055 switches are ON
when the logic is low and OFF when the logic is high. This
architecture allows these devices to be used as a single
SPST switch or as a distribution switch to distribute a single
source to two different loads.
SPST operation is achieved by using one of the signal pins
while floating the other signal pin or by externally connecting
the two signal pins together. When both signal pins are tied
together, the rON of the SPST is reduced by half, from 1Ω to
0.5Ω (when operated with a 5V supply).
Targeted applications include battery powered equipment

that benefit from low rON resistance, excellent rON flatness,
and fast switching speeds (tON = 12ns, tOFF = 12ns). The
digital logic input is 1.8V logic compatible when using a
single 2.7V to +3.6V supply and TTL compatible when the
supply is > +3.6V.
The ISL54054 and the ISL54055 are offered in a 6 Ld
1.2mmx1.0mmx0.5mm μTDFN package, alleviating board
space limitations.
The ISL54054 has two normally open (NO) switches and the
ISL54055 has two normally closed (NC) switches.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are 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.

4. VIN = input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
