Negative Signal Swing, Sub-ohm, Dual
SPDT Single Supply Switch
Features
• Pb-Free (RoHS Compliant)
• Negative Signal Swing (Max 6.5V Below V+)
• ON-Resistance (r
The Intersil ISL54059 device is a low ON-resistance, low
voltage, bi-directional, 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 down to 6.5V below
the positive supply rail. Targeted applications include battery

in a small form factor package, alleviating board space
limitations. It is available in a tiny 10 Ld 1.8x1.4mm µTQFN or

The ISL54059 is a committed dual single-pole/double-throw
(SPDT) that consists 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.
