TRI-STATE Octal D-Type Flip-Flop  
General Description  
The MM54HCT573/MM74HCT573 octal D-type latches and  
MM54HCT574/MM74HCT574 Octal D-type flip flops ad-  
vanced silicon-gate CMOS technology, which provides the  
inherent benefits of low power consumption and wide power  
supply range, but are LS-TTL input and output characteristic  
& pin-out compatible. The TRI-STATE outputs are capable  
of driving 15 LS-TTL loads. All inputs are protected from  
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.  
MM54HCT/MM74HCT devices are intended to interface be-  
tween TTL and NMOS components and standard CMOS  
devices. These parts are also plug in replacements for LS-  
TTL devices and can be used to reduce power consumption  
in existing designs.  
damage due to static discharge by internal diodes to V  
and ground.  
CC  
When the MM54HCT573/MM74HCT573 LATCH ENABLE  
input is high, the Q outputs will follow the D inputs. When  
the LATCH ENABLE goes low, data at the D inputs will be  
retained at the outputs until LATCH ENABLE returns high  
again. When a high logic level is applied to the OUTPUT  
CONTROL 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.
