SEMICONDUCTOR TECHNICAL DATA

The MC14516B synchronous up/down binary counter is constructed with

MOS P–channel and N–channel enhancement mode devices in a monolithic

structure.

L SUFFIX

CERAMIC

CASE 620

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.

P SUFFIX

PLASTIC

CASE 648

D SUFFIX

SOIC

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, pre-

cautions must be taken to avoid applications of

any voltage higher than maximum rated volt-

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.
