EPIC(Enhanced-Performance Implanted

Inputs Are TTL-Voltage Compatible  
description/ordering information  
This octal buffer/driver is designed specifically to  
improve both the performance and density of 3-state  
memory-address drivers, clock drivers, and  
bus-oriented receivers and transmitters.  
The SN74AHCT244 is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs.  
When OE is low, the device passes data from the A inputs to the Y outputs. 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 shall be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
