Qualification Pedigree  
2-V to 6-V VCC Operation  
Inputs Accept Voltages to 6 V  
Max tpd of 7.5 ns at 5 V  
(1) Component qualification in accordance with JEDEC and  
industry standards to ensure reliable operation over an  
extended temperature range. This includes, but is not limited  
to, Highly Accelerated Stress Test (HAST) or biased 85/85,  
temperature cycle, autoclave or unbiased HAST,  
electromigration, bond intermetallic life, and mold compound  
life. Such qualification testing should not be viewed as  
justifying use of this component beyond specified  
performance and environmental limits.  
DESCRIPTION  
This octal buffer and line driver is designed specifically to improve the performance and density of 3-state  
memory address drivers, clock drivers, and bus-oriented receivers and transmitters.  
The SN74AC244-EP device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs.  
When OE is low, the device passes noninverted 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 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.
