NOTES:
1. Address A18 is a NC for the IDT70T3319. Also, Addresses A18 and A17 are NC's for the IDT70T3399.
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.

Industrial and Commercial Temperature Ranges
NOTES:
1. VDD, OPTX, and VDDQX must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
2. OPTX selects the operating voltage levels for the I/Os and controls on that port.
If OPTX is set to VDD (2.5V), then that port's I/Os and controls will operate at 3.3V
levels and VDDQX must be supplied at 3.3V. If OPTX is set to VSS (0V), then that
port's I/Os and address controls will operate at 2.5V levels and VDDQX must be
supplied at 2.5V. The OPT pins are independent of one another—both ports can
operate at 3.3V levels, both can operate at 2.5V levels, or either can operate
at 3.3V with the other at 2.5V.
3. When REPEATX is asserted, the counter will reset to the last valid address loaded
via ADSX.
4. 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. It is recommended that
boundry scan not be operated during sleep mode.
5. Address A18x is a NC for the IDT70T3319. Also, Addresses A18x and A17x are
NC's for the IDT70T3399.
6. Chip Enables and Byte Enables are double buffered when PL/FT = VIH, i.e., the
signals take two cycles to deselect.
