NOTES:
1. Address A
17
is a NC for the IDT70T3599. Also, Addresses A
17
and A
16
are NC's for the IDT70T3589.
2. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. All static inputs, i.e., PL/FTx and OPTx
and the sleep mode pins themselves (ZZx) are not affected during sleep mode.
