Description

The FSA1256, FSA1257, and FSA1258 are high perfor-mance dual Single Pole/Single Throw (SPST) analog switches. These devices feature ultra low R_ON of 1.1 maximum at 4.5V VCC and will operate over the wide V_CCrange of 1.65V to 5.5V. These devices are fabricated with sub-micron CMOS technology to achieve fast switching speeds and are designed for break-before-make operation.The select input is TTL level compatible. The FSA1256 fea-tures two Normally Open (NO) switches. The FSA1257 features two Normally Closed (NC) switches. The FSA1258 has one NO switch and one NC switch.
