Octal inverting buffer (3-State)
74ABT240
FEATURES
• Octal bus interface
DESCRIPTION
The 74ABT240 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 74ABT240 device is an octal inverting 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/extraction permitted

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.

1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. This parameter is valid for any V between 0V and 2.1V, with a transition time of up to 10msec. From V = 2.1V to V 5V ± 10% a
