Octal transceiver with direction pin (3-State)  
74ABT245  
FEATURES  
• Octal bidirectional bus interface  
DESCRIPTION  
The 74ABT245 high-performance BiCMOS device combines low  
static and dynamic power dissipation with high speed and high  
output drive.  
• 3-State buffers  
• Output capability: +64 mA/–32 mA  
• Latch-up protection exceeds 500 mA per Jedec Std 17  
The 74ABT245 device is an octal transceiver featuring non-inverting  
3-State bus compatible outputs in both send and receive directions.  
The control function implementation minimizes external timing  
requirements. The device features an Output Enable (OE) input for  
easy cascading and a Direction (DIR) input for direction control.  
• ESD protection exceeds 2000 V per MIL STD 833 Method 3015  
and 200 V per Machine Model  
• Power-up 3-State  
• Live insertion/extraction permitted  
• 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.
