CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. Extended operation above the recommended operating conditions could result in decreased reliability. The Absolute Maximum Ratings are stress only ratings and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on NC, NO, IN, or COM exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
3. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
DescriptionThe 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 (0.29) 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 consist 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 compatible with the NLAS5223 and NLAS5223L.
