ISL54059

Negative Signal Swing, Sub-ohm, Dual

SPDT Single Supply Switch

The Intersil ISL54059 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

power consumption (8nA) and fast switching speeds

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.
