ISL54047
Ultra Low ON-Resistance, High Off-
Isolation, Single Supply, Diff SPST Analog
Switch
The Intersil ISL54047 device is a low ON-resistance, low
voltage, high off-isolation, bidirectional, differential single-
pole/single-throw (SPST) analog switch. It was designed to
operate from a single +1.65V to +4.5V supply. Targeted
applications include battery powered equipment that benefit
from low RON (0.44Ω) and fast switching speeds (tON = 40ns,
tOFF = 35ns). The digital logic input is 1.8V logic-compatible
when using a single +3V supply.
The ISL54047 has been designed with a T-switch
architecture. This approach results in maximum off-isolation
while retaining a low impedance signal path when switches
are ON.
The device can be used as a low impedance bypass element
for noisy amplifier circuits.
The ISL54047 has two normally open (NO) SPST switches
that are controlled by a single logic control pin.
