scope:

This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). Two product assurance classes consisting of military high reliability (device classes Q and M) and space application (device class V), and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). Device class M microcircuits represent non-JAN class B microcircuits in accordance with 1.2.1 of MIL-STD-883, "Provisions for the use of MIL-STD-883 in conjunction with compliant non-JAN devices". When available, a choice of Radiation Hardness Assurance (RHA) levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device class M RHA marked devices shall meet the MIL-I-38535 appendix A specified RHA levels and shall be marked with the appropriate RHA designator. Device classes Q and V RHA marked devices shall meet the MIL-I-38535 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type(s) shall identify the circuit function as follows:

Device type Generic number Circuit function Full scale error 01 LTC1291B 2 Channel 12-Bit Serial I/O Data Acquisition System ±0.5 LSB 02 LTC1292B 1 Channel 12-Bit Serial I/O Data Acquisition System ±0.5 LSB 03 LTC1293B 6 Channel 12-Bit Serial I/O Data Acquisition System ±0.5 LSB 04 LTC1294B 8 Channel 12-Bit Serial I/O Data Acquisition System ±0.5 LSB 05 LTC1291C 2 Channel 12-Bit Serial I/O Data Acquisition System ±1.0 LSB 06 LTC1292C 1 Channel 12-Bit Serial I/O Data Acquisition System ±1.0 LSB 07 LTC1293C 6 Channel 12-Bit Serial I/O Data Acquisition System ±1.0 LSB 08 LTC1294C 8 Channel 12-Bit Serial I/O Data Acquisition System ±1.0 LSB 09 LTC1291D 2 Channel 12-Bit Serial I/O Data Acquisition System ±4.0 LSB 10 LTC1292D 1 Channel 12-Bit Serial I/O Data Acquisition System ±4.0 LSB 11 LTC1293D 6 Channel 12-Bit Serial I/O Data Acquisition System ±4.0 LSB 12 LTC1294D 8 Channel 12-Bit Serial I/O Data Acquisition System ±4.0 LSB

The device class designator shall be a single letter identifying the product assurance level as follows:

Device class Device requirements documentation M Vendor self-certification to the requirements for non-JAN class B microcircuits in accordance with 1.2.1 of MIL-STD-883 Q or V Certification and qualification to MIL-I-38535

The case outline(s) shall be as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style E GDIP1-T16 or CDIP2-T16 16 Dual-in-line P GDIP1-T8 or CDIP2-T8 8 Dual-in-line R GDIP1-T20 or CDIP2-T20 20 Dual-in-line

The lead finish shall be as specified in MIL-STD-883 (see 3.1 herein) for class M or MIL-I-38535 for classes Q and V. Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
