description  
This 10-bit bus-interface flip-flop is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVC821A features 3-state outputs designed specifically for driving highly capacitive or relatively  
low-impedance loads. They are particularly suitable for implementing wider buffer registers, I/O ports,  
bidirectional bus drivers with parity, and working registers.  
The ten flip-flops are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK) input, the  
device provides true data at the Q outputs.  
A buffered output-enable (OE) input can be used to place the ten 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  
thebuslinessignificantly. Thehigh-impedancestateandincreaseddriveprovidethecapabilitytodrivebuslines  
without interface or pullup components.  
OE does not affect the internal operations of the latch. Previously stored 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 these devices as translators  
in a mixed 3.3-V/5-V system environment.  
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 SN74LVC821A is characterized for operation from –40°C to 85°C.
