Absolute Maximum Ratings(Note 1)
Supply Voltage
7V
Input Voltage
7V
Operating Free Air Temperature Range 0°C to +70°C
Storage Temperature Range
−65°C to +150°C
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the “Electrical
Characteristics” table are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.

Note 2: The symbols (↓, ↑) indicate the edge of the clock pulse used for reference: ↑ for rising edge, ↓ for falling edge.
Note 3: Setup and hold times are with reference to the enable input.
Note 4: The select-to-enable setup time is the time before the HIGH-to-LOW enable transition that the select must be stable so that the correct latch is
selected and the others not affected.
Note 5: TA = 25°C and VCC = 5V.
