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.
