description  
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVCH16244A 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.  
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.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74LVCH16244A is characterized for operation from –40°C to 85°C.
