Description

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 Ω maximum at 4.5 V

VCC. The FSA1256, FSA1257, and FSA1258 operate

over a wide VCC range of 1.65 V to 5.5 V. The

FSA1256A, FSA1257A, and FSA1258A operation range

is 2.7 V to 5.5 V. 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.
