Note 1: “Absolute Maximum Ratings” are those beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should

be operated at these limits. The table of “Electrical Characteristics” provide conditions for actual device operation.

Note 2:

All input and/or output pins shall not exceed VCC plus 0.5V and shall not exceed the absolute maximum rating at anytime, including power-up and

power-down. This prevents the ESD structure from being damaged due to excessive currents flowing from the input and/or output pins to QV CC and VCC. There is

a diode between each input and/or output to VCC which is forward biased when incorrect sequencing is applied. Alternatively, a current limiting resistor can be used

when pulling-up the inputs to prevent damage. The current into any input/output pin shall be no greater than 50 mA. Exception, LI and Bn pins do not have power

sequencing requirements with respect to VCC and QVCC. Furthermore, the difference between VCC and QVCC should never be greater than 0.5V at any time including

power-up.

Note 3: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified.

All typical values are specified under these conditions.: VCC = 5V and TA = 25˚C unless otherwise stated.

Note 4: Only one output should be shorted at a time, and duration of the short should not exceed one second.

Note 5: Referenced to appropriate signal ground. Do not exceed maximum power dissipation of package.
