DESCRIPTION/ORDERING INFORMATION  
The SN74LVC574A octal edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V VCC operation.  
This device features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance  
loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working  
registers.  
On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels at the data (D) inputs.  
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.  
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of thIs device as a translator in  
a mixed 3.3-V/5-V system environment.
