BIDIRECTIONAL SHIFT REGISTER SHIFTING PULSE IN BOTH FORWARD AND BACKWARD DIRECTIONS

摘要

When the forward shift pulse, by a second transistor 16 off, thereby preventing a through current flows between the fifth transistor and the seventh transistor. When the reverse shift pulse, and by the fifteenth transistor is OFF, the through current is prevented from flowing between the fifth transistor and the sixth transistor. Accordingly, it is prevented that the potential fluctuation occurs in the output signal of the shift register to shift between the forward pulse and the reverse pulse shift. ; Sheet program register, a pulse, a transistor, a through-current, the potential variation
