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
