NOTES:
1. Industrial temperature range product for 20ns speed grade is available as a standard device. All other speed grades are available by special order.
2. Writing data to the mail1 register when the B0-B35 outputs are active and MBB is HIGH.
3 Writing data to the mail2 register when the A0-A35 outputs are active and MBA is HIGH.
4. Only applies when reading data from a mail register.
