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_ONof 0.75Ω (typical) and will operate

Features

■ Maximum 0.9Ω On Resistance (R_ON) for 4.5V supply

at 25°C

■ 0.3Ω maximum R_ONflatness for 4.5V supply

over the wide V_CCrange of 1.65V to 5.5V. The devices are

■ Broad V_CCoperating range: 1.65V to 5.5V

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.

■ Fast turn-on and turn-off time

■ Over-voltage tolerant TTL compatible control input

■ Available in SC70 and MicroPak space saving surface

mount packages

Note 1: The “Absolute Maximum Ratings” are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum rating.
