Quad buffer (3-State)
74ABT126
FEATURES
• Quad bus interface
• 3-State buffers
DESCRIPTION
The 74ABT126 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
• Live insertion/extraction permitted
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per JEDEC Std 17
The 74ABT126 device is a quad buffer that is ideal for driving bus
lines. The device features four Output Enables (OE0, OE1, OE2,
OE3), each controlling one of the 3-State outputs.
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
• Power-up 3-State
• 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.

NOTES:
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 to10msec. From V = 2.1V to V = 5V ± 10%, a
