All Maximum 1.1 On Resistance (R ) for ON devices feature ultra-low R of 1.1 maximum at 4.5 V ON 4.5 V Supply V . The FSA1256, FSA1257, and FSA1258 operate CC over a wide V range of 1.65 V to 5.5 V. The CC 0.4 Max. R Flatness for 4.5 V Supply ON FSA1256A, FSA1257A, and FSA1258A operation range Space-Saving Pb-Free MicroPak Packaging is 2.7 V to 5.5 V. These devices are fabricated with sub- micron CMOS technology to achieve fast switching Broad V Operating Range: CC speeds and are designed for break-before-make - FSA1256, FSA1257, FSA1258: 1.65 V to 5.5 V operation. The select input is TTL level compatible. The - FSA1256A, FSA1257A, FSA1258A: 2.7 V to FSA1256 and FSA1256A feature two Normally Open 5.5 V (NO) switches. The FSA1257 and FSA1257A feature two Normally Closed (NC) switches. The FSA1258 and Fast Turn-On and Turn-Off Times FSA1258A have one NO switch and one NC switch. FSA1258, FSA1258A Feature Break-Before-Make Enable Circuitry IMPORTANT NOTE: Over-Voltage Tolerant TTL-Compatible Control Input For additional performance information, please contact analogswitch fairchildsemi.com.
