FSA4157 Low Voltage 1 SPDT Analog Switch
General Description
FSA4157 is a high performance Single Pole/Double Throw (SPDT) analog switch. The device features ultra low RON of 1.15 maximum at 4.5V VCC and will operate over the wide VCC range of 1.65V to 5.5V. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL level compatible.

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. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: The input and output negative ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Control input must be held HIGH or LOW and it must not float.

Note 4: Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the voltage on the two (A or B Ports). Note 5: RON = RON max - RON min 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.
