DESCRIPTION
The 74ABT540 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT540 device is an octal inverting buffer that is ideal for
driving bus lines. The device features input and outputs on opposite
sides of the package to facilitate printed circuit board layout.
