2. The maximum package power dissipation is calculated using a junction temperature of 150  and a board trace length of 750 mils.

The SN74ACT16245Q-EP is a 16-bit bus transceiver organized as dual-octal noninverting 3-state transceivers and designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
The SN74ACT16245Q-EP device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The enable (G) input can be used to disable the devices so that the buses are effectively isolated.
