Overview
The MC14174B, produced by onsemi, is a hex type D flip-flop integrated circuit. It is constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. This device is designed to transfer data from the D inputs to the Q outputs on the positive edge of the clock pulse. All six flip-flops share common clock and reset inputs, with the reset being active low and independent of the clock.
