These parameters are not production tested. 5. The internal address strobe is always active. 6. In FIFO mode, td1 = 425 ns (min) between reads of the receiver FIFO and the status registers (interrupt identification register and line status register). write cycle timing requirements over recommended ranges of operating free-air temperature and supply voltage (see Note 7 and Figure 5) MIN MAX UNIT tw5 Pulse duration, IOW ↓ 80 ns tsu4 Setup time, CSx valid before IOW ↓ (see Note 8) 15 ns tsu5 Setup time, A2 – A0 valid before IOW ↓ (see Note 8) 15 ns tsu6 Setup time, DB0 – DB7 valid before IOW ↑ 15 ns th3 Hold time, A2 – A0 valid after IOW ↑ (see Note 8) 20 ns th4 Hold time, CSx valid after IOW ↑ (see Note 8) 20 ns th5 Hold time, DB0 – DB7 valid after IOW ↑ 15 ns td3 Delay time, tsu5 + tw5 + td4 175 ns td4 Delay time, IOW ↑ to IOW or IOR ↓ 80 ns NOTES: 7. These parameters are not production tested. 8. The internal address strobe is always active. read cycle switching characteristics over recommended ranges of operating free-air temperature and supply voltage, CL = 100 pF (see Note 9 and Figure 4) PARAMETER MIN MAX UNIT tpd1 Propagation delay time from IOR ↓ to BDO ↑ or from IOR ↑ to BDO ↓ 60 ns ten Enable time from IOR ↓ to DB0–DB7 valid (see Note 10) 60 ns tdis Disable time from IOR ↑ to DB0–DB7 released (see Note 10) 60 ns NOTES: 9. These parameters are not production tested. 10. VOL and VOH (and the external loading) determine the charge and discharge time. |
