Low RON Low Voltage Dual SPST Analog Switch

with Low ICCT “A” Option

General Description

The

FSA1256,

FSA1256A,

FSA1257,

FSA1257A,

FSA1258, and FSA1258A are high performance dual Sin-

gle 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 Nor-

mally 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.
