TECHNICAL DATA
IW4060B
14-Stage Ripple-Carry Binary
Counter/Divider and Oscillator
High-Voltage Silicon-Gate CMOS
The IW4060B 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-Q’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 OSC In
(and OSC Out). Schmitt trigger action on the input-pulse line permits
unlimited input-pulse rise and fall times.
