DESCRIPTION

The 74ABT16244A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT16244A device is a 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE

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

3OE Two options are available, 74ABT16244A which does not have the bus hold feature and 74ABTH16244A which incorporates the bus hold feature.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. 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 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
