The UTC CD4069 is a CMOS IC with six inverter circuits and
designed for using of wide power supply operating range, low power
consumption, high noise immunity, and symmetric controlled rise
and fall times. The IC is capable of ESD protection by diode clamps
to VDD and VSS.
* Wide supply voltage range: 3.0V ~ 15V.
* High noise immunity: 0.45 VDD typ.
* Low Power TTL compatibility: Fan out of 2 driving 74L
or 1 driving 74LS.
