Quad buffer (3-State)
74ABT125
FEATURES
* Quad bus interface * 3-State buffers * Live insertion/extraction permitted * Output capability: +64mA/-32mA * Latch-up protection exceeds 500mA per Jedec Std 17 * ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
DESCRIPTION
The 74ABT125 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT125 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.
* 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 150C. 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 VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V 10% a transition time of up to 100sec is permitted.
