description  
This 18-bit universal bus driver is designed for  
1.65-V to 3.6-V V operation.  
A8  
A9  
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)  
inputislow. TheAdataislatchediftheclock(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.

To ensure the high-impedance state during power  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.  
LE  
Active bus-hold circuitry is provided to hold  
unused or floating data inputs at a valid logic level.

The SN74ALVCH16834 is characterized for  
operation from –40°C to 85°C.
