Low R Low Voltage Dual SPST Analog Switch  
ON  
General Description  
The FSA1256, FSA1257, and FSA1258 are high perfor-  
mance dual Single Pole/Single Throw (SPST) analog  
switches. These devices feature ultra low RON of 1.1  
Features  
Maximum 1.1On Resistance (RON) for 4.5V supply  
0.4max RON flatness for 4.5V supply  
Space saving Pb-Free MicroPak packaging  
Broad VCC operating range: 1.65V to 5.5V  
maximum at 4.5V VCC and will operate over the wide VCC  
range of 1.65V 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 fea-  
tures two Normally Open (NO) switches. The FSA1257  
features two Normally Closed (NC) switches. The  
FSA1258 has one NO switch and one NC switch.  
Fast turn-on and turn-off time  
FSA1258 features break-before-make enable circuitry  
Over-voltage tolerant TTL compatible control input

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 ratings.  
The “Recommended Operating Conditions” table will define the conditions  
for actual device operation.

Note 4: On Resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.  
Note 5: RON = RONmax RONmin measured at identical VCC, temperature, and voltage.  
Note 6: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
