MM74HC574
3-STATE Octal D-Type Edge-Triggered Flip-Flop
General Description
The MM74HC574 high speed octal D-type flip-flops utilize
advanced silicon-gate P-well CMOS technology. They pos-
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 devices are ide-
ally 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 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 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 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.
