HEF4029BT规格书详情
DESCRIPTION
The HEF4029B 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).
Information on P0 to P3 is asynchronously loaded into the counter while PL is HIGH, independent of CP.
The counter is advanced one count on the LOW to HIGH transition of CP when CE and PL are LOW. The TC signal is normally HIGH and goes LOW when the counter reaches its maximum count in the UP mode, or the minimum count in the DOWN mode provided CE is LOW.
