M74HC374 is a high-speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS NON INVERTING fabricated with sub-micron silicon gate C2MOS technology. This 8 bit D-TYPE FLIP FLOP is controlled by a clock input (CK) and an output 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. While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and while OE is high 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 be retained or the new data can be entered even while the outputs are off. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
The M74HC374 is a high‑speed CMOS octal D‑type flip‑flop featuring three‑state, non‑inverting outputs. It operates with a clock input (CK) and an active‑low output‑enable input (OE), allowing data to be latched on the rising edge of the clock while the outputs can be placed in high‑impedance mode.
