General Description

The HEF4510B is an edge-triggered synchronous up/down BCD counter with a clock input (CP), an up/down count control input (UP/DN), an active LOW count enable input (CE), an asynchronous active HIGH parallel load input (PL), four parallel inputs (P0 to P3), four parallel outputs (O0 to O3), an active LOW terminal count output (TC), and an overriding asynchronous master reset input (MR).

Information on P0 to P3 is loaded into the counter while PL is HIGH, independent of all other input conditions except the MR input, which must be LOW.

With PL LOW, the counter changes on the LOW to HIGH transition of CP if CE is LOW.
