ISL54053
Ultra Low ON-Resistance, Low Voltage, Single Supply, SPDT Analog Switch FN6460
Rev. 3.00
October 19, 2009 The Intersil ISL54053 device is a low ON-resistance,
low voltage, bidirectional, single pole/double throw
(SPDT) analog switch designed to operate from a
single +1.8V to +5.5V supply. Targeted applications
include battery powered equipment which benefit
from low rON (0.8пЃ—) and fast switching speeds (tON =
24ns, tOFF = 10ns). The digital logic input is 1.8V
logic compatible when using a single +3.0V supply. Features Cell phones, for example, often face ASIC
functionality limitations. The number of analog input
or GPIO pins may be limited and digital geometries
are not well suited to analog switch performance. This
part may be used to “mux-in” additional functionality
while reducing ASIC design risk. The ISL54053 is
offered in the 6 Ld 1.2mmx1.0mmx0.5mm ВµTDFN
and 6 Ld SOT-23 packages, alleviating board space
limitations. rON matching between channels . 0.004пЃ—пЂ The ISL54053 is a committed SPDT that consists of
one normally open (NO) and one normally closed
(NC) switch. This configuration can also be used as a
2-to-1 multiplexer. …
