ISL84684IR-T中文资料Intersil数据手册PDF规格书

The Intersil ISL84684 device is a low ON-resistance, low

voltage, bidirectional, dual single-pole/double-throw (SPDT)

analog switch designed to operate from a single +1.65V to

+3.6V supply. Targeted applications include battery powered

equipment that benefits from low rON (0.35Ω) and fast

switching speeds (tON = 50ns, tOFF = 27ns). The digital logic

input is 1.8V logic-compatible when using a single +3V supply.

Cell phones, for example, often face ASIC functionality

limitations. The number of analog input or GPIO pins may be

limited and digital geometries are not well suited to analog

switch performance. This part may be used to “mux-in”

additional functionality while reducing ASIC design risk. The

ISL84684 is offered in small form factor packages, alleviating

board space limitations.

The ISL84684 is a committed dual single-pole/double-throw

(SPDT) that consists of two normally open (NO) and two

normally (NC) switches. This configuration can be used as a

dual 2-to-1 multiplexer. The ISL84684 is pin compatible with

the MAX4684 and MAX4685.
