MM74HC574
MM74HC574 is 3-State Octal D-Type Edge-Triggered Flip-Flop manufactured by onsemi.
feature
, these devices are ideally suited for interfacing with bus lines in a bus organized system.
These devices are 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 patible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground. Features

- Low Input Current: 1 m A Maximum
- Low Quiescent Current: 80 m A Maximum
- patible with Bus- oriented Systems
- Output Drive Capability: 15 LS- TTL Loads
