Enable / Disable Function
pin #1 (e/d control)
open
high ”1” (V_IH ≥ 0.8 V_DC)
low ”0” (V_IL ≤ 0.2 V_DC)
disabled conditions:
• internal oscillator active
• output disabled, high impedance
pin #3 (output)
undefined
active
high impedance
enable condition:
• pull the e/d pin to „H“ if the oscillator
should always be enabled
