MM74HC574WM (ON SEMICONDUCTOR)

The MM74HC574WM is a 3-state octal D-type Edge-triggered Flip-Flop utilize advanced silicon-gate P-well CMOS technology. It posses the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS-TTL loads. Due to the large output drive capability and the 3-state feature, this device is ideally suited for interfacing with bus lines in a bus organized system. This device is positive edge triggered flip-flops. Data at the D inputs, meeting the set-up and hold time requirements, are transferred to the Q outputs on positive going transitions of the clock (CK) input. When a high logic level is applied to the Output Control (OC) input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. The 74HC logic family is speed, function and pinout compatible with the standard 74LS logic family.
