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,
PIN CONNECTION
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.
