MC14516B

Binary Up/Down Counter

The MC14516B synchronous up/down binary counter is

constructed with MOS P鈭抍hannel and N鈭抍hannel 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鈭抰o鈭扗igital and Digital鈭抰o鈭扐nalog 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

applications of any voltage higher than maximum rated

voltages to this high鈭抜mpedance circuit. For proper

operation, V

outputs must be left open.

ORDERING INFORMATION

See detailed ordering and shipping information in the package

dimensions section on page 2 of this data sheet.

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.
