1 General description

The 74ALVT16244 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 and line driver featuring non-inverting 3-state bus outputs.

The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
