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.
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1
A at 18 V over full package-
temperature range; 100 nA at 18 V and 25
C
Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range
GND
(V
IN
or V

)
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
).
Unused outputs must be left open.
