QUICK REFERENCE DATA
DESCRIPTION
The 74ALVT16241 is a high-performance BiCMOS product
designed for V
CC
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.
