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 R
V
over a wide V
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.
