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

and V

out

should be constrained to the

range V

or V

out

)

Unused inputs must always be tied to an appropriate

logic voltage level (e.g., either V

or V

). Unused out-

puts must be left open.

NOTE: When counting up, the Carry Out

signal is normally high and is low only

when Q0 through Q3 are high and Carry In

is low. When counting down,

Carry Out

is low only when Q0 through Q3 and Carry In are low.
