CD4029BM/CD4029BC Presettable

Binary/Decade Up/Down Counter

General Description

The CD4029BM/CD4029BC is

presettable up/down

count in the ‘‘up’’ mode or the minimum count in the ‘‘down’’

mode provided the carry input is at logical ‘‘0’’ state.

counter which counts in either binary or decade mode de-

pending on the voltage level applied at binary/decade input.

When binary/decade is at logical ‘‘1’’, the counter counts in

binary, otherwise it counts in decade. Similarly, the counter

counts up when the up/down input is at logical ‘‘1’’ and vice

versa.

All inputs are protected against static discharge by diode

clamps to both V

and V

Features

Wide supply voltage range

High noise immunity

Low power

3V to 15V

0.45 V (typ.)

A logical ‘‘1’’ preset enable signal allows information at the

‘‘jam’’ inputs to preset the counter to any state asynchro-

nously with the clock. The counter is advanced one count at

the positive-going edge of the clock if the carry in and pre-

set enable inputs are at logical ‘‘0’’. Advancement is inhibit-

ed when either or both of these two inputs is at logical ‘‘1’’.

The carry out signal is normally at logical ‘‘1’’ state and goes

to logical ‘‘0’’ state when the counter reaches its maximum

fan out of 2

driving 74L

or 1 driving 74LS

TTL compatibility

Parallel jam inputs

Binary or BCD decade up/down counting
