description  
These 10-bit edge-triggered D-type flip-flops  
feature 3-state outputs designed specifically for  
driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable for  
implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.  
On the positive transition of the clock (CLK) input, the Q outputs are true to the data (D) input.  
A buffered output-enable (OE) input can place the ten outputs in either a normal logic state (high or low logic  
levels) or a high-impedance state. The outputs also are in the high-impedance state during power-up and  
power-down conditions. The outputs remain in the high-impedance state while the device is powered down. 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 operation of the flip-flops. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.  
The SN54ALS29821 is characterized for operation over the full military temperature range of 55°C to 125°C.  
The SN74ALS29821 is characterized for operation from 0°C to 70°C.
