H = HIGH Voltage Level, L = LOW Voltage Level, X = Don’t Care, NC = No Change, Z = High Impedance.
Unless otherwise noted, these limits are over the operating free-air temperature range.
Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
T
A
is the “instant on” case temperature.

The latch data inputs.
The latch enable input. The latches are transparent when LE is HIGH. Input data is latched on the
HIGH-to-LOW transition.
The three-state latch outputs.
The output enable control. When the OE is LOW, the outputs are enabled. When OE is HIGH, the outputs
Y

are in the high impedance (off) state.
