<p>PURPOSE:To always enable initialization without fail even when a power supply voltage rapidly rises at the latch circuit. CONSTITUTION:The respective emitters of two transistors Tr 1 and Tr 2 are connected to a ground, the mutual bases and collectors are connected, a power supply voltage Vcc of a DC power source is impressed through a diode D and a resistor R1 to the collector of the transistor Tr 1, the power supply voltage Vcc is impressed through a resistor R2 to the collector of the transistor Tr 2, a transistor Tr 3 for data input is parallelly connected to the transistor Tr 2, an output Q1 is extracted from the collector of the transistor Tr 1, and an inverted output Q2 is extracted from the collector of the transistor Tr 2.</p> |
