This circuit provides output pulses from each of pre-drive blocks E1 to EN and F1 to FN at half the frequency of input oscillator O driving latch L, with each of the blocks of the circuit beyond the latch having no more than two inputs each to provide a high speed circuit and with -SCAN C and -SCAN B inputs utilizing parts of the circuit for testing purposes. Latch L is a latch of the "D" type well known in the art and has the D and CLK input terminals respectively for data and controlling clock pulses. Latch L also has output terminals Q and Q. Oscillator O is connected with the CLK terminal of latch L.
