MM74HC574/D
MM74HC574
3-State Octal D-Type
Edge-Triggered Flip-Flop
The MM74HC574 high speed octal D−type flip−flops utilize
advanced silicon−gate P−well CMOS technology. They possess 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 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 compatible 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.
