Classic EPLD Family Data Sheet

Notes to tables:

(1)

See the Operating Requirements for Altera Devices Data Sheet in this data book.

(2)

Numbers in parentheses are for industrial-temperature-range devices.

(3)

The minimum DC input is –0.3 V. During transitions, the inputs may undershoot to –2.0 V (EP910) or

–0.5 V (EP910I) or overshoot to 7.0 V (EP910) or VCC + 0.5 V (EP910I) for input currents less than 100 mA and periods

less than 20 ns.

(4)

Maximum VCC rise time for EP910 devices = 50 ms; for EP910I devices, maximum VCC rise time is unlimited with

monotonic rise.

(5)

For all clocks: tR and tF = 100 ns (50 ns for the industrial-temperature-range version).

(6)

These values are specified in Table 15 on page 770.

(7)

The device capacitance is measured at 25

° C and is sample-tested only.

(8)

The IOH parameter refers to high-level TTL or CMOS output current; the IOL parameter refers to low-level TTL

output current.

(9)

This parameter does not apply to EP910I devices.

(10) When the Turbo Bit option is not set (non-Turbo mode), an EP910 device will enter standby mode if no logic

transitions occur for 100 ns after the last transition, and an EP910I device will enter standby mode if no logic

transitions occur for 75 ns after the last transition.

(11) Measured with a device programmed as a 24-bit counter.
