DESCRIPTION

The 74ALVT162241 is a high-performance BiCMOS product designed

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 30

W 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.
