FEATURES

resistors to hold unused inputs

the need for external pull up resistors to hold unused inputs

and 200V per Machine Model

DESCRIPTION

The 74ABT16240A is a high-performance BiCMOS device which

combines low static and dynamic power dissipation with high speed

and high output drive.

This device is an inverting 16-bit buffer that is ideal for driving bus

lines. The device features four Output Enables (1OE, 2OE, 3OE,

4OE), each controlling four of the 3-State outputs.

Two options are available, 74ABT16240A which does not have the

bus hold feature and 74ABTH16240A which incorporates the bus

hold feature.
