3-State Octal D-Type
Edge-Triggered Flip-Flop
MM74HC574
TSSOP20
MTC SUFFIX
CASE 948AQ
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.

DATA
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
2. For a power supply of 5 V 10% the worst−case output voltages (V , and V ) occur for HC at 4.5 V. Thus the 4.5 V values should be used
OH
OL
when designing with this supply. Worst−case V and V occur at V = 5.5 V and 4.5 V respectively. (The V value at 5.5 V is 3.85 V.)
IH
IL
CC
IH
The worst−case leakage current (I , I , and I ) occur for CMOS at the higher voltage and so the 6.0 V values should be used.
