QUICK REFERENCE DATA

DESCRIPTION

The 74ABT16241A is a high-performance BiCMOS device which combines low static and dynamic power dissipation with high speed and high output drive.

This device is a 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, 74ABT16241A which does not have the bus hold feature and 74ABTH16241A which incorporates the bus hold feature.
