description  
These 10-bit flip-flops feature 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 devices provide 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-impe-  
dance 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.  
NC – No internal connection  
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.  
When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT821 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74ABT821A is characterized for operation from –40°C to 85°C.
