CMOS 14-Stage Ripple-Carry Binary Counter/Divider and Oscillator
DESCRIPTION
UCD4060B consists of an oscillator section and 14 ripple-carry
binary counter stages. The oscillator configuration allows design of
either RC or crystal oscillator circuits. A RESET input is provided
which resets the counter to the all-O’s state and disables the
oscillator. A high level on the RESET line accomplishes the reset
function. All counter stages are master-slave flip-flops. The state of
the counter is advanced one step in binary order on the negative
transition of ФI and ФO. All inputs and outputs are fully buffered.
Schmitt trigger action on the input-pulse line permits unlimited
input-pulse rise and fall times.
FEATURES
* 12MHz clock rate at 15V

* Fully static operation
* Buffered inputs and outputs
* Schmitt trigger input-pulse line
Oscillator Features
* All active components on chip
* RC or crystal oscillator configuration
* RC oscillator frequency of 690 kHz min. at 15V |
