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 HEF4753B LSI transient-pulse suppression, pulse duration selector divider, counter, positive or negative edge delaying module or low-frequency control circuit. All manipulation possibilities depend on a time scaling, which is adjustable by the 8-bit programmable counter and the system clock. The system clock can be divided internally by 1, 16, 256 or 4096 as input clock for the counter. In all cases the manipulated input sequence appears at the only output OUT. Fig.1 Functional diagram.
