PURPOSE:To prevent unstableness of operations dependent upon phase shift of pulses, by operating a static binary counter only by a one-phase pulse signal. CONSTITUTION:When signal A is high-level and clock phi is high-level, transistors 60 and 55 are turned on. Consequently, signal C becomes low-level, and transistor 54 is turned on, and signal B becomes high-level. Signal A is held low-level by unit substance 44. When clock phi becomes low-level, transistors 65 and 66 are turned on, and signal B is held high-level. Transistors 51 and 52 are turned on, and signal A becomes high-level. When clock phi becomes high-level again, transistor 60 is turned on, and signal A is held high-level because transistors 61 and 62 are turned on. Since transistors 56 and 67 are turned on, signal B becomes low-level. |
