TABLE IA. Electrical performance characteristics - Continued.
1/ For tests not listed in the referenced MIL-STD-883 (e.g. VIH, VIL), utilize the general test procedure under the conditions listed
herein. All inputs and outputs shall be tested, as applicable, to the tests in table IA herein.
2/ Each input/output, as applicable shall be tested at the specified temperature for the specified limits. Output terminals not
designated shall be high level logic, low level logic, or open, except as follows:
a. VIC (pos) tests, the GND terminal can be open. TC = +25°C.
b. VIC (neg) tests, the VCC terminal shall be open. TC = +25°C.
c. All ICC tests, the output terminal shall be open. When performing these tests, the current meter shall be placed in the
circuit such that all current flows through the meter.
3/ RHA parts for device type 02 supplied to this drawing have been characterized through all levels M, D, P, L, R, and F of
irradiation. However, this device is only tested at the 'F' level. Pre and Post irradiation values are identical unless otherwise
specified in table IA. When performing post irradiation electrical measurements for any RHA level, TA = +25°C.
4/ For negative and positive voltage and current values, the sign designates the potential difference in reference to GND and the
direction of current flow, respectively; and the absolute value of the magnitude, not the sign, is relative to the minimum and
maximum limits, as applicable, listed herein.
5/ The VOH and VOL tests shall be tested at VCC = 3.0 V and 4.5 V. The VOH and VOL tests are guaranteed, if not tested, for other
values of VCC. Limits shown apply to operation at VCC = 3.3 V ±0.3 V and VCC = 5.0 V ±0.5 V. Tests with input current at
+50 mA or -50 mA are performed on only one input at a time with duration not to exceed 2 ms. Transmission driving tests
may be performed using VIN = VCC or GND. When VIN = VCC or GND is used, the test is guaranteed for VIN = VIH minimum
and VIL maximum.
6/ The VIH and VIL tests are not required if applied as forcing functions for VOH and VOL tests.
7/ The maximum limit for this parameter at 100 krads (Si) is 4 μA.
8/ Power dissipation capacitance (CPD) determines both the power consumption (PD) and dynamic current consumption (IS).
Where:
P
D = (CPD + CL) (VCC x VCC)f + (ICC x VCC)
I
S = (CPD + CL) VCCf + ICC
f is the frequency of the input signal and CL is the external output load capacitance.
9/ Tests shall be performed in sequence, attributes data only. Functional tests shall include the truth table and other logic
patterns used for fault detection. The test vectors used to verify the truth table shall, at a minimum, test all functions of each
input and output. All possible input to output logic patterns per function shall be guaranteed, if not tested, to the truth table in
figure 2 herein. Functional tests shall be performed in sequence as approved by the qualifying activity on qualified devices.
Allowable tolerances in accordance with MIL-STD-883 for the input voltage levels may be incorporated.
For VOUT measurements, L ≤ 0.3VCC and H ≥ 0.7VCC.
10/ AC limits at VCC = 5.5 V are equal to the limits at VCC = 4.5 V and guaranteed by testing at VCC = 4.5 V. AC limits at
VCC = 3.6 V are equal to limits at VCC = 3.0 V and guaranteed by testing at VCC = 3.0 V. Minimum AC limits for VCC = 5.5 V
are 1.0 ns and guaranteed by guardbanding the VCC = 4.5 V minimum limits to 1.5 ns. For propagation delay tests, all paths
must be tested.
11/ This parameter is guaranteed if not tested.
