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.
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
PIN CONNECTION
