5. DC Characteristics and
Timing Specifications
CII51005-4.0
Cyclone® II devices are offered in commercial, industrial, automotive,
and extended temperature grades. Commercial devices are offered in –6
(fastest), –7, and –8 speed grades.
Operating
Conditions
All parameter limits are representative of worst-case supply voltage and
junction temperature conditions. Unless otherwise noted, the parameter
values in this chapter apply to all Cyclone II devices. AC and DC
characteristics are specified using the same numbers for commercial,
industrial, and automotive grades. All parameters representing voltages
are measured with respect to ground.
Tables 5–1 through 5–4 provide information on absolute maximum
ratings.

Notes to Table 5–1:
(1) Conditions beyond those listed in this table cause permanent damage to a device. These are stress ratings only.
Functional operation at these levels or any other conditions beyond those specified in this chapter is not implied.
Additionally, device operation at the absolute maximum ratings for extended periods of time may have adverse
effect on the device reliability.
(2) Refer to the Operating Requirements for Altera Devices Data Sheet for more information.
(3) During transitions, the inputs may overshoot to the voltage shown in Table 5–4 based upon the input duty cycle.
The DC case is equivalent to 100% duty cycle. During transition, the inputs may undershoot to –2.0 V for input
currents less than 100 mA and periods shorter than 20 ns.
