PURPOSE:To obtain a driving circuit which is suitable for IC-implementation and provides low-speed driving operation, by using pnp transistors (TR) and npn TRs as thyristors. CONSTITUTION:When a clock pulse supplied to a clock pulse input terminal 12 is inverted from a low to a high potential state, an emitter current flows to the 2nd pnp TR24 and the 1st npn TR14 turns on. At this time, the 2nd npn TR23 turns off because its base potential is -VCE and +VCE, turning off the 1st pnp TR13. Similarly, when the clock pulse is inverted from the high to the low potential state, the 2nd npn TR23 turns on the 1st pnp TR13 and the 2nd pnp TR24 turns on the 1st npn TR14. |
