CD4029BC

Presettable Binary/Decade Up/Down Counter

maximum count in the “up” mode or the minimum count in

the “down” mode provided the carry input is at logical “0”

state.

General Description

The CD4029BC is a presettable up/down counter which

counts in either binary or decade mode depending on the

voltage level applied at binary/decade input. When binary/

decade is at logical “1”, the counter counts in binary, other-

wise 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_DDand V_SS

Features

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

preset enable inputs are at logical “0”. Advancement is

inhibited when either or both of these two inputs is at logi-

cal “1”. The carry out signal is normally at logical “1” state

and goes to logical “0” state when the counter reaches its

■ Wide supply voltage range: 3V to 15V

■ High noise immunity: 0.45 V_DD(typ.)

■ Low power TTL compatibility: fan out of 2 driving 74L

or 1 driving 74LS

■ Parallel jam inputs

■ Binary or BCD decade up/down counting
