The CD4069UB consists of six inverter circuits and is manufactured
using complementary MOS (CMOS) to achieve
wide power supply operating range, low power consumption,
high noise immunity, and symmetric controlled rise
and fall times.
This device is intended for all general purpose inverter
applications where the special characteristics of the
MM74C901, MM74C907, and CD4049A Hex Inverter/Buffers
are not required. In those applications requiring larger
noise immunity the MM74C14 or MM74C914 Hex Schmitt
Trigger is suggested.
All inputs are protected from damage due to static discharge
by diode clamps to VDD and VSS.
Features

Wide supply voltage range: 3.0V to 15V

High noise immunity: 0.45 VDD typ.

Low power TTL compatibility: Fan out of 2 driving 74L
or 1 driving 74LS

Equivalent to MM74C04
