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.
