+1.8V to +6.5V, High Off-Isolation, Dual
SPST Analog Switch with Negative Signal
www.dCataasphaeebt4iul.ictoym
The Intersil ISL54066 device is a low ON-resistance, high
off-isolation, low voltage, dual single-pole/single-throw (SPST)
analog switch. It was designed to operate from a single +1.8V
to +6.5V supply and can pass signals that swing 6.5V below
the positive supply rail. Targeted applications include battery
powered equipment that benefit from low rON (1Ω), high
off-isolation (80dB) and fast switching speeds (tON = 40ns,
tOFF = 30ns). The digital logic input is 1.8V logic-compatible
when using a single +3V supply.
The ISL54066 incorporates a T-switch architecture. This
approach results in excellent signal off-isolation while
retaining a low impedance signal path when switches are ON.
The ISL54066 is offered in small form factor packages,
alleviating board space limitations. The ISL54066 is available
in 10Ld µTQFN and TDFN packages.
The ISL54066 is a dual single-pole/single-throw (SPST)
normally open (NO) switch with independent logic control.
