Numbers in parentheses are for industrial-temperature-range devices.
(4)
V
must rise monotonically.
(5)
The POR time for all 7000S devices does not exceed 300
μ
s. The sufficient V
voltage level for POR is 4.5 V. The
device is fully initialized within the POR time after V
reaches the sufficient POR voltage level.
(6)
3.3-V I/ O operation is not available for 44-pin packages.
(7)
The V
parameter applies only to MAX 7000S devices.
(8)
During in-system programming, the minimum DC input voltage is –0.3 V.

These values are specified under the MAX 7000 recommended operating conditions in
Table 11 on page 23
.
(10) The parameter is measured with 50
%
of the outputs each sourcing the specified current. The I
OH
parameter refers
to high-level TTL or CMOS output current.
(11) The parameter is measured with 50
%
of the outputs each sinking the specified current. The I
OL
parameter refers to
low-level TTL, PCI, or CMOS output current.
(12) When the JTAG interface is enabled in MAX 7000S devices, the input leakage current on the JTAG pins is typically
–60
μ
A.
(13) Capacitance is measured at 25
°
C and is sample-tested only. The
OE1
pin has a maximum capacitance of 20 pF.

shows the typical output drive characteristics of MAX 7000
devices.

Timing Model
MAX 7000 device timing can be analyzed with the Altera software, with a
variety of popular industry-standard EDA simulators and timing
analyzers, or with the timing model shown in
Figure12
. MAX 7000
devices have fixed internal delays that enable the designer to determine
the worst-case timing of any design. The Altera software provides timing
simulation, point-to-point delay prediction, and detailed timing analysis
for a device-wide performance evaluation.
