DESCRIPTION The M54/74HCT374, M54/74HCT534, are high speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3STATE OUTPUTS fabricated with in silicon gate 2 C MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power comsuption. These8-bit D-type flip-flops are controlled by a clock input (CK) and an ouput enable input (OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs (HCT374) or their complements (HCT534). While the OE input is low, the eight outputs will be in a normal logic state (high or low logic level), and while high level, the outputs will be in a high impedance state. The output control does not affect the internal operation of flip-flops. That is, the old data can PIN CONNECTION (top view)
