Description
The Intersil ISL54059 device is a low $$-resistance, low voltage, bi-directi$$al, 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 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 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.
