1. General description
2. Features
3. Quick reference data
The 74ABT126 high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT126 device is a quad buffer that is ideal for driving bus lines. The device
features four output enable inputs (nOE each controlling one of the 3-state outputs (nY).
