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
), each controlling four of the 3-State outputs.
4OE
Two options are available, 74ABT16240A which does not have the
bus hold feature and 74ABTH16240A which incorporates the bus
hold feature.
