DESCRIPTION  
This 16-bit buffer/driver is designed for 1.65-V to  
3.6-V VCC operation.  
The SN74ALVCH162244 is designed specifically to  
improve the performance and density of 3-state  
memory address drivers, clock drivers, and  
bus-oriented receivers and transmitters.  
The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and  
symmetrical active-low output-enable (OE) inputs.  
The outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot and  
undershoot.  
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 is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVCH162244 is characterized for operation from -40°C to 85°C.
