description/ordering information  
The SN54LVC574A octal edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V V  
operation, and the  
operation.  
CC  
SN74LVC574A octal edge-triggered D-type flip-flop is designed for 1.65-V to 3.6-V V  
CC  
These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively  
low-impedance loads. They are 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.  
These devices are fully specified for partial-power-down applications using I . The I circuitry disables the  
off  
off  
outputs, preventing damaging current backflow through the device when it is powered down.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
