NOTES:
1. For 10ns speed grade only: Vcc = 3.3V +/-0.15V, TA = 0
° to +70°C; JEDEC JESD8-A compliant.
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. Industrial temperature range is available by special order.
