+1.8V to +6.5V, Sub-Ohm, Dual SPDT
Analog Switch with Negative Signal
Capability
The Intersil ISL54059 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
powered equipment that benefit from low r_ON (0.56Ω), low
power consumption (8nA) and fast switching speeds
(t_ON = 55ns, t_OFF = 18ns). The digital inputs are1.8V
logic-compatible up to a +3V supply. The ISL54059 is offered
in a small form factor package, alleviating board space
limitations. It is available in a tiny 10 Ld 1.8x1.4mm µTQFN or
10 Ld 3x3mm TDFN package.
The ISL54059 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.
