Abstract

PURPOSE:To make the power consumption at the frequency counter part of the time when no operations are required nearly zero when crystal oscillation type watch function and frequency counter function are integrated with I<2>L gates and achieve lower power consumption as a whole by using two external power sources. CONSTITUTION:In the integrated circuit device constituting crystal oscillation type watch function and frequency counter function by using the I<2>L gates G1 thru G6 wherein opposite structure vertical transistors whose emitters and collectors are made opposite from those of ordinary bipolar transistors are used as transistors for inverters and transistors of complementary type having the bases and emitters of said transistors commonly as their collectors and bases are used as transistors for injectors, the watch counter part I is normally driven by the first external power source VCC1 and the block II including the frequency counter 9 is driven by the second external power source VCC2 only when its operation is required.
