74ABT241Octal buffer/line driver (3-State)
FEA TURES
•Octal bus interface
•3-State buffers
•Power-up 3-State
•Output capability: +64mA/–32mA
DESCRIPTION
The 74ABT241 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT241 device is an octal buffer that is ideal for driving bus
lines. The device features two Output Enables (1OE
controlling four of the 3-State outputs.
, 2OE), each
•Latch-up protection exceeds 500mA per Jedec Std 17
•ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
•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.
