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-typeflip-flops (witha gating structureto provide
T-type flip-flop capability) connected as counters.
These counterscan be clearedby a high level on
the RESET line, and can be preset to any binary
number presenton 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 clockof the next stage. IftheUP/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 providesa cleanclock signal
to the subsequentcounting stage.
