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 down 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 are 1.8V
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.
