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 r
ON
of the SPST is
reduced by half, from 1 to 0.5 (when operated with
a 5V supply).
Targeted applications include battery powered
equipment that benefit from low r
ON
resistance,
excellent r
ON
flatness, and fast switching speeds (t
ON
= 12ns, t
OFF
= 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 is offered in a 6 Ld
1.2mmx1.0mmx0.5mm
TDFN
and 6 Ld SOT-23
packages. The ISL54055 is offered in a 6 Ld
1.2mmx1.0mmx0.5mm
TDFN,
alleviating board
space limitations.
The ISL54054 has two normally open (NO) switches
and the ISL54055 has two normally closed (NC)
switches.

10. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this
data sheet.
11. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
12. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal
