The 4029 is a synchronous edge-triggered up/down 4-bit binary/BCD decade counter with a
clock input (CP), an active LOW count enable input (CE
), an up/down control input (UP/
DN
), a binary/decade control input (BIN/DEC), an overriding asynchronous active HIGH
parallel load input (PL), four parallel data inputs (P0 to P3), four parallel buffered outputs
(O0 to O3) and an active LOW terminal count output (TC
).
