Binary Up/Down Counter
The MC14516B synchronous up/down binary counter is
constructed with MOS Pchannel and Nchannel enhancement mode
devices in a monolithic structure.
This counter can be preset by applying the desired value, in binary,
to the Preset inputs (P0, P1, P2, P3) and then bringing the Preset
Enable (PE) high. The direction of counting is controlled by applying
a high (for up counting) or a low (for down counting) to the
UP/DOWN input. The state of the counter changes on the positive
transition of the clock input.
Cascading can be accomplished by connecting the Carry Out to the
Carry In of the next stage while clocking each counter in parallel. The
outputs (Q0, Q1, Q2, Q3) can be reset to a low state by applying a high
to the reset (R) pin.
This CMOS counter finds primary use in up/down and difference
counting. Other applications include: (1) Frequency synthesizer
applications where low power dissipation and/or high noise immunity
is desired, (2) AnalogtoDigital and DigitaltoAnalog conversions,
and (3) Magnitude and sign generation.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

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 highimpedance circuit. For proper
operation, V
in
and V
out
should be constrained to the
range V
SS
(V

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