DESCRIPTION

The HCF4510B and HCF4516B are monolithic

integrated circuits available in 16-lead dual in-line

plastic

and

plastic

micro

package.

The

HCF4510B Presettable BCD Up/Down Counter

and the HCF4516B Presettable Binary Up/Down

Counter consist of four synchronously clocked

D-type flip-flops (with a gating structure to provide

T-type flip-flop capability) connected as counters.

These counters can be cleared by a high level on

the RESET line, and can be preset to any binary

number present on the jam inputs by a high level

on the PRESET ENABLE line. The HCF4510B

will count out of non-BCD counter states in a

maximum of two clock pulses in the up mode,

and a maximum of four clock pulses in the down

mode. If the CARRY-IN input is held low, the

counter

advances

up

or

down

on

each

positive-going

clock

transition.

Synchronous

cascading is accomplished by connecting all

clock inputs in parallel and connecting the

CARRY-OUT of a less significant stage to the

CARRY-IN of a more significant stage. The

HCF4510B and HCF4516B can be loaded in the

ripple mode by connecting the CARRY-OUT to

the clock of the next stage. If the UP/DOWN input

changes

during

a

terminal

count,

the

CARRY-OUT must be gated with the clock, and

the UP/DOWN input must change while the clock

is high. This method provides a clean clock signal

to the subsequent counting stage.
