+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 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 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.
