NOTES:
H = High-voltage level
h = HIGH state must be present one set-up time before the LOW-to-HIGH clock transition
L = Low-voltage level
l = LOW state must be present one set-up time before the LOW-to-HIGH clock transition
NC= No change
X = Don’t care
Z = High impedance “off” state
↑ = LOW-to-HIGH clock transition
↑ = Not LOW-to-HIGH clock transition
Disable outputs
ABSOLUTE MAXIMUM RATINGS
Operation beyond the limit set forth in this table may impair the useful life of the device.
Unless otherwise noted these limits are over the operating free air temperature range.
