Ultra Low ON-Resistance, High Off-

Isolation, Single Supply, Diff SPST Analog

Switch

Features

• T-Switch Architecture

• OFF-Isolation at 100kHz

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

• R

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.

• Single Supply Operation . . . . . . . . . . . . . . . +1.65V to +4.5V

• Low Power Consumption (P ). . . . . . . . . . . . . . . <0.45μW

• Fast Switching Action (V+ = +4.3V)

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.
