描述
The ISL54064 device is a low ON-resistance, low voltage, bidirectional, dual single-pole/single-throw (SPST) 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 (20nA) and fast switching speeds (tON = 55ns, tOFF = 18ns). The digital inputs are 1.8V logic-compatible up to a +3V supply. The ISL54064 also features integrated circuitry to eliminate click and pop noise to an audio speaker. This device is offered in a small form factor package, alleviating board space limitations. It is available in a tiny 10 Ld 1.8mm x 1.4mm µTQFN or 10 Ld 3mm x 3mm TDFN package. The ISL54064 is a committed dual single-pole/single-throw (SPST) that consists of two normally closed (NC) switches with independent logic control.
