DESCRIPTION/ORDERING INFORMATION  
The SN74LVC374A 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. This device is particularly suitable for implementing buffer registers, input/output (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 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 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 internal operations of the latch. Old data can be retained or new data can be entered while  
the outputs are in the high-impedance state.  
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.  
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.
