DESCRIPTION
The HEF4753B is a universal timer module for counting and dividing as well as for event-recognition and manipulation of input sequences.
The following functions are included: synchronization and edge-detection of the input signal, programmable counter, clock divider with different lengths, operating mode decoder, control logic and output multiplexer.
Depending on the operating mode and the application, the circuit works as a presettable 8-bit counter with transient-pulse suppression, pulse duration selector divider, counter, positive or negative edge delaying module or low-frequency control circuit.
