H = HIGH voltage level

L = LOW voltage level

X = Don’t care

Z = High impedance “off” state

↑ = LOW-to-HIGH level transition

NOTES:

1. Output level before the indicated steady-state input conditions

were established, provided that CP is high before LE goes low.

2. Output level before the indicated steady-state input conditions

were established.
