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.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
