Binary/Decade Up/Down

Counter

The MC14029B Binary/Decade up/down counter is constructed with MOS

P–channel and N–channel enhancement mode devices in a single

monolithic structure. The counter consists of type D flip–flop stages with a

gating structure to provide toggle flip–flop capability. The counter can be

used in either Binary or BCD operation. This complementary MOS counter

finds primary use in up/down and difference counting and frequency

synthesizer applications where low power dissipation and/or high noise

immunity is desired. It is also useful in A/D and D/A conversion and for

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

• Asynchronous Preset Enable Operation

• Capable of Driving Two Low–power TTL Loads or One Low–power

Schottky TTL Load Over the Rated Temperature Range
