MC14516B Datasheet, PDF (1/12 Pages) ON Semiconductor – Binary Up/Down Counter

MC14516B
Binary Up/Down Counter
The MC14516B synchronous up/down binary counter is
constructed with MOS P–channel and N–channel 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) Analog–to–digital and digital–to–analog conversions,
and (3) Magnitude and sign generation.

This device contains protection circuitry to guard
against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid ap-
plications 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 V_SS v (V_in or V_out) v V_DD.
Unused inputs must always be tied to an appropriate
logic voltage level (e.g., either V_SS or V_DD). Unused out-
puts must be left open.
