LOW or MBF1 HIGH

Propagation Delay Time, CLKA↑ to B0-B35(1)and CLKB↑ to A0-A35(2)

Propagation Delay Time, MBA to A0-A35 valid and MBB to B0-B35 valid

Propagation Delay Time, MRS1 or PRS1 LOW to AEB LOW, AFA HIGH, and MBF1 HIGH

and MRS2 or PRS2 LOW to AEA LOW, AFB HIGH, and MBF2 HIGH

Enable Time, CSA or W/RA LOW to A0-A35 Active and CSB LOW and W/RB

HIGH to B0-B35 Active

Disable Time, CSA or W/RA HIGH to A0-A35 at high impedance and CSB HIGH

or W/RB LOW to B0-B35 at high impedance.

NOTES:

1. Writing data to the mail1 register when the B0-B35 outputs are active and MBB is HIGH.

2. Writing data to the mail2 register when the A0-A35 outputs are active and MBA is HIGH.

3. Industrial temperature range is available by special order.
