MC14516B
The MC14516B synchronous up/down binary counter is constructed with
MOS P–channel and N–channel enhancement mode devices in a monolithic
structure.
This counter can be preset by applying the desired value, in binary, to the
Preset inputs (P0, P1, P2, P3) and then bringing the Preset Enable (PE)
high. T he 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 c an be accomplished by connecting the Carry Out
to the
Carry In
of the next stage while clocking e ach counter in parallel. The
outputs (Q0, Q1, Q2, Q3) 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 a nd digital–to–analog conversions, a nd (3) Magnitude and sign
generation.
• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Internally Synchronous for High Speed
• Logic Edge–Clocked Design — Count Occurs on Positive Going Edge
of Clock
• Single Pin Reset
• Asynchronous Preset Enable Operation
• Capable of Driving Two Low–Power TTL Loads or One Low–Power
Schottky Load Over the Rated Temperature Range

Carry Out
is low only when Q0 through Q3 and Carry In are low.

BLOCK DIAGRAM
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of
any voltage higher than maximum rated voltages to this high–impedance circuit. For proper
operation, Vin and V
out
should be constrained
to the range VSS v (Vin or V
out
) v VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either V
SS
or VDD). Unused outputs must be left open.
VDD = PIN 16
