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 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 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.
