NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are

exceeded. Functional operation should be restricted to RECOMMENDED OPER-

ATING CONDITIONS. Exposure to higher than recommended voltages for

extended periods of time could affect device reliability.

*VIL (min) = – 0.5 V dc; VIL (min) = – 2.0 V ac (pulse width ≤ 20 ns) for I ≤ 20.0 mA.

** VIH (max) = VCC + 0.3 V dc; VIH (max) = VCC + 2.0 V ac (pulse width ≤ 20 ns) for I ≤ 20.0 mA.

This is a synchronous device. All synchro-

nous inputs must meet specified setup and hold

times with stable logic levels for

ALL rising

edges of clock (K) while the device is selected.

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages or electric fields; however, it is advised

that normal precautions be taken to avoid

application of any voltage higher than maxi-

mum rated voltages to these high–impedance

circuits.
