1 / 14 page 1 ® FN6584.1 ISL54066 Negative Signal Swing, High Off-Isolation, Dual SPST Single Supply Switch 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 down to 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.
