BCD up/down counter
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. 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.
