Binary/Decade Up/Down Counter
●TheMC14029B Binary/Decade up/down counter isconstructed with MOS P–channeland N–channel enhancement mode devices in a single monolithicstructure. The counter consists of type D flip–flop stages with a gatingstructure to provide toggle flip–flop capability. The counter can be
●usedin either Binaryor BCD operation. This complementary MOS counter findsprimary use in up/down and difference counting and frequency synthesizerapplications where low power dissipationand/or high noise immunityis 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
●• Pin for Pin Replacement for CD4029B
