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.
