Operation of these devices with standard TTL or DTL may require the use of appropriate pull-up resistors to insure a minimum logic “1”.
Undervoltage lockout is guaranteed to release device at no more than 4.5V and disable the device at no less than 3.0V input logic voltage.

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 OUTPUT ENABLE will set all outputs to
the off condition, regardless of any other input conditions.
When the OUTPUT ENABLE is low, the outputs depend on
the state of their respective latches. If current shutdown is
activated, the OUTPUT ENABLE must be pulsed high to
restore operation and reset the Flag. Over temperature
faults are not latched and require no reset pulse.
