+1.8V to +6.5V, Sub-ohm, Click and Pop
Elimination, Dual SPDT w/ Enable, Analog
Switch with Negative Signal Capability
The Intersil ISL54065 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 up to 6.5V below
the positive supply rail. Targeted applications include battery
powered equipment that benefit from low rON (0.56Ω), low
power consumption (8nA) and fast switching speeds
(tON = 55ns, tOFF = 18ns). The digital inputs are1.8V
logic-compatible up to a +3V supply. The ISL54065 also
features integrated circuitry to eliminate click and pop noise to
an audio speaker.
The ISL54065 is offered in a small form factor package,
alleviating board space limitations. It is available in a tiny
12 Ld 2.2x1.4mm µTQFN.
The ISL54065 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.

Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin, V+ and GND. One of these
diodes conducts if any analog signal exceeds the
recommended analog signal range.
Virtually all the analog switch leakage current comes from
the ESD diodes and reversed biased junctions in the switch
cell. Although the ESD diodes on a given signal pin are
identical and therefore fairly well balanced, they are reverse
biased differently. Each is biased to either the +Ring or -Ring
and the analog input signal. This means their leakages will
vary as the signal varies. The difference in the two diode
leakages to the +Ring or -Ring and the reverse biased
junctions at the internal switch cell constitutes the
analog-signal-path leakage current.
