Control Input Voltage (VIN)

0V to VCC

Switch Input Voltage (VIN)

0V to VCC

Output Voltage (VOUT)

0V to VCC

Operating Temperature (TA)

− 40° C to + 85° C

Input Rise and Fall Time (tr, tf)

 

Control Input VCC = 4.0V to 5.5V

Note 1: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The datasheet specifica- tions should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading vari- ables. Fairchild does not recommend operation outside datasheet specifi- cations.

Note 2: Control input must be held HIGH or LOW, it must not float.

Note 3: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.

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 voltages on the two (A or B Ports).

Note 5: Per TTL driven Input (VIN = 3.4V, Control input only). A and B pins do not contribute to ICC.
