HEF4516B MSI Information on P0 to P3 is loaded into the counter while PL is HIGH, independent of all other input conditions except MR which must be LOW. When PL and CE are LOW, the counter changes on the LOW to HIGH transition of CP. Input UP/DN determines the direction of the count, HIGH for counting up, LOW for counting down. When counting up, TC is LOW when O0 and O3 are HIGH and CE is LOW. When counting down, TC is LOW when O0 to O3 and CE are LOW. A HIGH on MR resets the counter (O0 to O3 = LOW) independent of all other input conditions. Fig.2 Pinning diagram.
