DATASHEET ISL54053 FN6460 Rev. 3.00 Ultra Low ON-Resistance, Low Voltage, Single Supply, SPDT Analog Switch October 19, 2009 The Intersil ISL54053 device is a low ON-resistance, Features low voltage, bidirectional, single pole/double throw Drop In replacement for the NLAS5123 (SPDT) analog switch designed to operate from a single +1.8V to +5.5V supply. Targeted applications ON-resistance (r ) ON include battery powered equipment which benefit -V = +5.0V . 0.8 CC from low r (0.8) and fast switching speeds (t = ON ON -V = +3.0V . 1.1 CC 24ns, t = 10ns). The digital logic input is 1.8V OFF -V = +1.8V . 2.3 CC logic compatible when using a single +3.0V supply. r matching between channels . 0.004 ON Cell phones, for example, often face ASIC functionality limitations. The number of analog input r flatness (+4.5V supply) . 0.25 ON or GPIO pins may be limited and digital geometries Single supply operation . +1.8V to +5.5V are not well suited to analog switch performance. This Fast switching action (+4.5V supply) part may be used to mux-in additional functionality -t 24ns ON while reducing ASIC design risk. The ISL54053 is -t . 10ns offered in the 6 Ld 1.2mmx1.0mmx0.5mm TDFN OFF and 6 Ld SOT-23 packages, alleviating board space Guaranteed break-before-make limitations. ESD HBM rating . >6kV The ISL54053 is a committed SPDT that consists of 1.8V CMOS logic compatible (+3V supply) one normally open (NO) and one normally closed Available in 6 Ld TDFN and 6Ld SOT-23 Packages (NC) switch. This configuration can also be used as a 2-to-1 multiplexer. Pb-free (RoHS compliant) TABLE 1.
