description  
This 20-bit flip-flop is designed specifically for  
low-voltage (3.3-V) V operation; it is tested at  
CC  
2.5-V, 2.7-V, and 3.3-V V  
.
CC  
The SN74ALVC16721’s 20 flip-flops are edge-  
triggered D-type flip-flops with qualified clock  
storage. On the positive transition of the clock  
(CLK) input, the device provides true data at the  
Q outputs if the clock-enable (CLKEN) input is low.  
If CLKEN is high, no data is stored.

A buffered output-enable (OE) input places the  
20 outputs in either a normal logic state (high  
or low level) or a high-impedance state. In the  
high-impedance state, the outputs neither load  
CLKEN  
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.  
Active bus-hold circuitry holds unused or floating data inputs at a valid logic level.  
The SN74ALVC16721 is available in TI’s shrink small-outline (DL) and thin shrink small-outline (DGG)  
packages, which provide twice the I/O pin count and functionality of standard small-outline packages in the  
same printed-circuit-board area.  
The SN74ALVC16721 is characterized for operation from 40°C to 85°C.
