NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied.
Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
2. VCC, Control and Switch terminals.
NOTES:
1. Capacitance is characterized but not tested.
2. TA = 25°C, f = 1MHz, VIN = 0V, VOUT = 0V
NOTES:
1. Typical values are at VCC = 5.0V, +25°C ambient.
2. The voltage drop between the indicated ports divided by the current through the switch.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
