MAX 7000B Programmable Logic Device Data Sheet
Notes to tables:
(1)
(2)
Minimum DC input voltage is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 4.6 V
for input currents less than 100 mA and periods shorter than 20 ns.
(3)
All pins, including dedicated inputs, I/O pins, and JTAG pins, may be driven before VCCINT and VCCIO are
powered.
(4)
(5)
The parameter is measured with 50% of the outputs each sourcing the specified current. The IOH parameter refers
to high-level TTL or CMOS output current.
(6)
The parameter is measured with 50% of the outputs each sinking the specified current. The IOL parameter refers to
low-level TTL or CMOS output current.
(7)
This value is specified for normal device operation. During power-up, the maximum leakage current is ±300 μA.
(8)
This pull-up exists while devices are being programmed in-system and in unprogrammed devices during
power-up. The pull-up resistor is from the pins to VCCIO.
(9)
Capacitance is measured at 25° C and is sample-tested only. Two of the dedicated input pins (OE1 and GCLRN) have
a maximum capacitance of 15 pF.
(10) The POR time for all 7000B devices does not exceed 100 μs. The sufficient VCCINT voltage level for POR is 2.375 V.
The device is fully initialized within the POR time after VCCINT reaches the sufficient POR voltage level.
(11) These devices support in-system programming for –40° to 100° C. For in-system programming support between
–40° and 0° C, contact Altera Applications.
