DESCRIPTION
The 74ALVT162241 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. 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. The 74ALVT162241 is designed with 30W series resistance in both High and Low output stages. This design reduces the line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters. The series termination resistors reduce overshoot and undershoot and are ideal for driving memory arrays.

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 150C. 3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
