+1.8V to +6.5V, Sub-Ohm, Dual SPDT
Analog Switch with Negative Signal
Capability and Click and Pop Elimination
Features
• Pb-free (RoHS Compliant)
• Negative Signal Capability
The Intersil ISL54062 device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
analog switch. It is designed to operate from a single +1.8V to
+6.5V supply and pass signals that swing up to 6.5V below
the positive supply rail. Targeted applications include battery

The ISL54062 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally closed (NC) switches with independent logic control.
This configuration can be used as a dual 2-to-1 multiplexer.
