1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
NOTE:
1. 1.5V undershoots are allowed for 10ns once per cycle.

NOTES:
1. Not more than one output should be shorted at a time and duration of the short-circuit should not exceed one second. Guaranteed but not tested.
2. IDT72403 only.
3. Tested with outputs open (IOUT = 0). OE is HIGH for IDT72403.
4. For frequencies greater than 10MHz, ICC = 35mA + (1.5mA x [f –10MHz]) commercial, and ICC = 45mA + (1.5mA x [f –10MHz]) military.
5. Military availability for IDT72403 is 10MHz, 35MHz. IDT72401 is available for all MHz.
