description  
This 16-bit universal bus driver is designed for  
1.65-V to 3.6-V V operation.  
CC  
Data flow from A to Y is controlled by the  
output-enable (OE) input. The device operates in  
the transparent mode when the latch-enable (LE)  
input is low. When LE is high, the A data is latched  
if the clock (CLK) input is held at a high or low logic  
level. If LE is high, the A data is stored in the  
latch/flip-flop on the low-to-high transition of CLK.  
When OE is high, the outputs are in the  
high-impedance state.  
NC – No internal connection  
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 SN74ALVCH16334 is characterized for operation from –40°C to 85°C.
