operation, but with the capability to  
CC  
The eight flip-flops of the ′LVT574 are edge-triggered D-type flip-flops. On the positive transition of the clock  
(CLK) input, the Q outputs are set to the logic levels set up 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 a 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 need for 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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN74LVT574 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.  
The SN54LVT574 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74LVT574 is characterized for operation from –40°C to 85°C.
