MIL-M-38510-753 Microcircuits, Digital, Advanced Cmos, Flip-Flops, Monolithic Silicon, Positive LogicThis specification covers the detail requirements for monolithic silicon, advanced CMOS, logic microcircuits. Two product assurance classes and a choice of case outlines, lead finishes, and radiation hardness assurance RHA are provided and are reflected in the complete Part or Identifying Number PIN. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535 see 6.3.

MIL-M-38510/753B

TABLE III.  Delta limits at 25°C.

1/  The above parameters shall be recorded before and

after the required burn-in and life tests to determine deltas ().

4.4.4  Group D inspection.  Group D inspection shall be in accordance with table V of MIL-PRF-38535.  End-point electrical parameters shall be as specified in table II herein.

4.4.5  Group E inspection.  Group E inspection is required only for parts intended to be marked as radiation hardness assured (see 3.7 herein).  RHA levels for device classes B and S shall be as specified in MIL-PRF-38535.

a.  End-point electrical parameters shall be as specified in table II herein.

b.  For device classes B and S, subgroups 1 and 2 in table V, method 5005 of MIL-STD-883 shall be tested as appropriate for construction.

c.   When specified in the purchase order or contract, a copy of the RHA delta limits shall be supplied.

d.  RHA tests for device classes B and S for levels M, D, P, L, R, and F shall be performed through each level to determine at what levels the devices meet the RHA requirements.  These RHA tests shall be performed for initial qualification and after design or process changes which may affect the RHA performance of the devices.

e.  Prior to total dose irradiation, each selected sample shall be assembled in its qualified package.  It shall pass the specified group A electrical parameters in table I for subgroups specified in table II herein.

d.  For device classes B and S, the devices shall be subjected to radiation hardness assurance tests as specified in MIL-PRF-38535 for the RHA level being tested.  All device classes must meet the postirradiation end-point electrical parameter limits as defined in table I at TA = +25°C ±5°C, after exposure, to the subgroups specified in table II herein.

4.4.5.1  Total dose irradiation testing.  Total dose irradiation testing shall be performed in accordance with MIL-STD-883, method 1019, condition A, and as specified herein.  Prior to and during total dose irradiation characterization and testing, the devices for characterization shall be biased so that 50 percent are at inputs high and 50 percent are at inputs low, and the devices for testing shall be biased to the worst case condition established during characterization.  Devices shall be biased as follows:

a.  Input tested high, VCC = 5.5 V dc +5%,  RCC  = 10ν ±20%, VIN  = 5.0 V dc +5%, RIN  = 1 kν ±20%, and all outputs are open.

b.  Inputs tested low, VCC  = 5.5 V dc +5%, RCC  = 10ν ±20%, VIN  = 0.0 V dc, RIN  = 1 kν ±20%, and all outputs are open.

4.4.5.1.1  Accelerated aging test.  Accelerated aging shall be performed on class B and S devices requiring an RHA level greater that 5k rads (Si).  The post-anneal end point electrical parameter limits shall be as specified in table I herein and

shall be the preirradiation end point electrical parameter limit at +25°C ±5°C.  Testing shall be performed at initial qualification and after any design or process changes which may affect the RHA response of the device.
