DATASHEET ISL54050 FN6356 Rev 4.00 Ultra Low ON-Resistance, +1.65V to +4.5V, Single Supply, Dual SPDT Analog Nov 22, 2008 Switch The Intersil ISL54050 device is a low ON-resistance, low Features voltage, bidirectional, dual single-pole/double-throw (SPDT) Pin Compatible Replacement for the NLAS5223 and analog switch designed to operate from a single +1.65V to NLAS5223L +4.5V supply. Targeted applications include battery powered ON-Resistance (r ) equipment that benefit from low r (0.29 and fast ON ON - V+ = +4.3V 0.29 switching speeds (t = 40ns, t = 20ns). The digital logic ON OFF - V+ = +3.0V 0.33 input is 1.8V logic-compatible when using a single +3V supply. - V+ = +1.8V 0.55 Cell phones, for example, often face ASIC functionality r Matching Between Channels .0.06 ON limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog r Flatness Across Signal Range 0.03 ON switch performance. This part may be used to mux-in Single Supply Operation +1.65V to +4.5V additional functionality while reducing ASIC design risk. The Low Power Consumption (P ) .<0.45W D ISL54050 is offered in small form factor package, alleviating board space limitations. Fast Switching Action (V+ = +4.3V) -t . 40ns ON The ISL54050 is a committed dual single-pole/double-throw -t 20ns OFF (SPDT) that consists of two normally open (NO) and two ESD HBM Rating >8kV normally closed (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer. The ISL54050 is pin Break-before-Make compatible with the NLAS5223 and NLAS5223L. 1.8V Logic Compatible (+3V supply) TABLE 1.
