Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to absolute maximum ratings.

Electrical Characteristics

Over recommended operating free air temperature range (unless otherwise noted).

Notes:

1. All typical values are at V

CC

=

5V, T

A

=

25°C.

2. The output conditions have been chosen to produce a current that closely approximates one half of the true

short-circuit output current, I

OS

.

3. With the outputs open, CLK INH and CLK at 4.5V, and a clock pulse applied to the SH/LD

input, I

CC

is measured first

with the parallel inputs at 4.5V, then with the parallel inputs grounded.

Switching Characteristics
