FSA1256(A) / FSA1257(A) / FSA1258(A) Low-RON Low-Voltage, Dual SPST Analog Switch with Low-ICCT "A" Option Features Description FSA1256A, FSA1257A, FSA1258A feature low ICCT when S Input is lower than VCC Maximum 1.1 On Resistance (RON) for 4.5V supply 0.4 max RON flatness for 4.5V supply The FSA1256, FSA1256A, FSA1257, FSA1257A, FSA1258, and FSA1258A are high performance dual Single Pole/Single Throw (SPST) analog switches. All devices feature ultra low RON of 1.1 maximum at 4.5V VCC. The FSA1256, FSA1257, and FSA1258 operate over a wide VCC range of 1.65V to 5.5V. The FSA1256A, FSA1257A, and FSA1258A operation range is 2.7V 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 and FSA1256A feature two Normally Open (NO) switches. The FSA1257 and FSA1257A feature two Normally Closed (NC) switches. The FSA1258 and FSA1258A have one NO switch and one NC switch.
