DESCRIPTION

HCF4516B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP package.

It is a PRESETTABLE BINARY UP/DOWN

COUNTER, consists of four synchronously

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

provide T-type flip-flop capability) connected as a

counter. This counter 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. 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. HCF4516B can be

cascaded in the ripple mode by connecting all

clock inputs in parallel and 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.
