MM74HC574

  The MM74HC574 high speed octal D-type flip-flops utilize

  sess 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, these MM74HC574 are ide-ally suited for interfacing with bus lines in a bus organized system.

  These MM74HC574 are positive edge triggered flip-flops.Data at the D inputs,meeting the set-up and hold time require-ments,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 of MM74HC574 go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.

  The MM74HC574 is speed, function, and pinout com-patible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to V_CC and ground.
