DESCRIPTION

The HEF4527B is a BCD rate multiplier with two buffered rate outputs (O1 and O1), two buffered terminal count outputs (TC and TC), four BCD rate select inputs (SA, SB, SC, SD), a common clock input (CP), a preset input (PL), an overriding asynchronous clear input (CL), a strobe input (STR), a cascade input (CAS) and an active LOW count enable input (CE).

The BCD rate multiplier provides an output pulse rate based upon the BCD input number. For example, if 6 is the BCD number, there will be six output pulses for every ten clock input pulses. The output is clocked on the negative-going transition of the clock.
