Description
The 4510 is a synchronous up/down BCD counter with edge-triggered capability. It can count up or down in a BCD pattern depending on the input state. The counter has four input and four output pins dedicated to BCD input and output, respectively. The BCD output is provided on four parallel output pins: O0, O1, O2, and O3. O3 represents the most significant bit (MSB).
When the parallel load (pin1) is set to high, the BCD data is loaded from the input to the output pins. If the parallel load is low, the data remains unchanged. The Up/Down pin determines whether the counter counts up or down.
When the clock enable pin is set low, the counting process occurs on a low-to-high transition at the clock input. In other words, when a specific clock edge occurs under the relevant clock-enabling condition, the counter increases or decrements its value.
When the terminal count (pin7) reaches 1111 (15 in decimal) in up-counting mode or 0000 (0 in decimal) in down-counting mode, the output goes low. This sends a signal when the counter reaches its maximum or minimum value.
