Nov 22, 2008 Ultra Low ON-Resistance, +1.65V to +4.5V, Single Supply, Dual SPDT Analog
Switch
The Intersil ISL54050 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
+4.5V supply. Targeted applications include battery powered
equipment that benefit from low rON (0.29пЃ—пЂ© and fast
switching speeds (tON = 40ns, tOFF = 20ns). 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
ISL54050 is offered in small form factor package, alleviating
board space limitations.
The ISL54050 is a committed dual single-pole/double-throw
(SPDT) that consists of two normally open (NO) and two
normally closed (NC) switches. This configuration can be
used as a dual 2-to-1 multiplexer. The ISL54050 is pin …
