FSA1156 • FSA1157 Low RON Low Voltage SPST Analog Switch

FSA1156 • FSA1157

Low R

Low Voltage SPST Analog Switch

General Description

The FSA1156 and FSA1157 are high performance Single

Pole/Single Throw (SPST) analog switches. The devices

feature ultra low R

of 0.75Ω (typical) and will operate

over the wide V

range of 1.65V to 5.5V. The devices are

fabricated with sub-micron CMOS technology to achieve

fast switching speeds. The select input is TTL level com-

patible. The FSA1156 has Normally Open operation and

the FSA1157 has Normally Closed operation.

Features

■ Maximum 0.9Ω On Resistance (R

) for 4.5V supply

at 25

°C

■ 0.3

Ω maximum R

flatness for 4.5V supply

■ Broad V

operating range: 1.65V to 5.5V

■ Fast turn-on and turn-off time

■ Over-voltage tolerant TTL compatible control input

■ Available in SC70 and MicroPak

 space saving surface

mount packages

■ Available in Lead (Pb) Free MicroPak packaging
