For switch time specifications, see propagation
delay times in Section 5.5.
Inputs must not be pushed more than 0.5V above VDD or below VEE.
For input voltage level specifications for
control inputs, see VIH and VIL in Section 5.5.
Recommended output conditions:
Outputs must not be pulled above VDD or below VEE.
Input and output current consideration:
The CDx4HCx405x series of parts do not have internal current-drive circuitry, and thus cannot sink or source current. Any current will be passed through the device.
