description  
GND 10

These octal edge-triggered D-type flip-flops  
feature 3-state outputs designed specifically for  
bus driving. They are particularly suitable for  
implementing buffer registers, I/O ports,  
bidirectional bus drivers, and working registers.

A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal logic  
state (high or low logic levels) or the  
high-impedance state. In the high-impedance  
state, the outputs neither load nor drive the bus  
lines significantly. The high-impedance state and  
increased drive provide the capability to drive bus  
lines without interface or pullup components.

OE does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.  
The SN54HCT574 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74HCT574 is characterized for operation from –40°C to 85°C.
