Ultra Low ON-Resistance, Low Voltage, Single
Supply, Single SPST/1:2 Distribution Analog Switch
ISL54054, ISL54055
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 1Ω to 0.5Ω (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
μTDFN
and 6 Ld SOT-23
packages. The ISL54055 is offered in a 6 Ld
1.2mmx1.0mmx0.5mm
μTDFN,
alleviating board space
limitations.
The ISL54054 has two normally open (NO) switches and
the ISL54055 has two normally closed (NC) switches.
