1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating ratings.
3. Micrel CMOS devices have input-static protection but are susceptible to damage when exposed to extremely high static electrical charges.
4. Specification for packaged product only.
5. Operation of these devices with standard TTL or DTL may require the use of appropriate pull-up resistors to insure a minimum logic “1”.

Information present at an input is transferred to its latch
when the STROBE is high. A high CLEAR input will set all
latches to the output OFF condition regardless of the data
or STROBE input levels. A high /OE will set all outputs to
the off condition, regardless of any other input conditions.
When the /OE is low, the outputs depend on the state of
