The 20 flip-flops of the SN74ALVCH162721 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.  
CLKEN  
A buffered output-enable (OE) input places the 20  
outputs in either a normal logic state (high or low  
level) or the high-impedance state. In the  
high-impedance state, the outputs neither load  
NC – No internal connection  
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.  
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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot and  
undershoot.  
The SN74ALVCH162721 is characterized for operation from –40°C to 85°C.
