FEATURES  
DESCRIPTION  
• Octal bus interface  
The 74ABT244 high-performance BiCMOS device combines low  
static and dynamic power dissipation with high speed and high  
output drive.  
• 3-State buffers  
• Output capability: +64mA/–32mA  
• Latch-up protection exceeds 500mA per Jedec Std 17  
The 74ABT244 device is an octal buffer that is ideal for driving bus  
lines. The device features two Output Enables (1OE, 2OE), each  
controlling four of the 3-State outputs.  
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015  
and 200 V per Machine Model  
• Power-up 3-State  
• Live insertion capacity  
• Inputs are disabled during 3-State mode

NOTES:  
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the  
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to  
absolute-maximum-rated conditions for extended periods may affect device reliability.  
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction  
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.  
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
