The MM74HC374 high-speed octal D-type flip-flop utilizes an advanced silicon-gate CMOS process. The device has the high noise immunity and low power consumption of a standard CMOS integrated circuit, plus the ability to drive 15 LS-TTL loads. Due to their large output drive capability and 3-state nature, these devices are suitable for interfacing bus lines in bus organizing systems. These devices are positive-edge triggered flip-flops. When the clock (CK) input transitions positively, data from the D input that meets the setup and hold time requirements is transferred to the Q output. Applying a high logic level to the output control (OC) input puts all outputs into a high-impedance state, regardless of the signals present at the other inputs and the state of the storage elements. The 74HC logic family is compatible with the standard 74LS logic family in speed, functionality, and pinout. All inputs are protected against damage due to electrostatic charge by internal diodes clamped to VCC and ground.
