MC14510B
The MC14510B synchronous up/down BCD counter is constructed with
MOS P–channel and N–channel enhancement mode devices in a monolithic
structure. The counter consists of type D flip–flop stages with a gating
structure to provide type T flip–flop capability.
This counter can be preset by applying the desired value in BCD to the
Preset inputs (P1, P2, P3, P4) and then bringing the Preset Enable (PE)
high. The direction of counting is controlled by applying a high (for up
counting) or a low (for down counting) to the UP/DOWN input. The state of
the counter changes on the positive transition of the clock input.
Cascading can be accomplished by connecting the Carry Out to the
Carry In of the next stage while clocking each counter in parallel. The
outputs (Q1, Q2, Q3, Q4) can be reset to a low state by applying a high to the
Reset (R) pin.
This CMOS counter finds primary use in up/down and difference counting.
Other applications include: (1) Frequency synthesizer applications where
low power dissipation and/or high noise immunity is desired, (2) Analog–to–
digital and digital–to–analog conversions, and (3) Magnitude and sign
generation.

NOTE: When counting up, the Carry Out signal is normally high, and is low only
when Q1 and Q4 are high and Carry In is low. When counting down, Carry
Out is low only when Q1 through Q4 and Carry In are low.

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.
