Supply voltage and drive strength
The SN74ALB16244DGG: Each of the four elements drives 25mA per channel in both high and low states, enough to fan out to multiple CMOS loads or drive a short PCB trace without an external buffer. The 3-state output lets you share a data bus across multiple devices — the outputs go high-impedance when the enable line is inactive, preventing bus contention.
