This 20-bit bus-interface flip-flop is designed for  
1.65-V to 3.6-V VCC operation.  
The SN74ALVCH16821 can be used as two 10-bit  
flip-flops or one 20-bit flip-flop. The 20 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 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 need for 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.  
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.  
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.
