DESCRIPTION
The
4N51-4N54
an on-board decoder/driver and memory (except 4N53). These displays are hermetically sealed and conform to MIL-PRF-87157, the
general specification for light emitting diode displays. The character height is 7.4mm (.29”). The green LED version conforms to
MIL-D-87157 with exception of color.
The 4N51 is a numeric display which decodes positive BCD logic into the numbers “0-9”, a “-” sign, a right-hand decimal point, and a
test pattern (all LED’s on).
series are solid state numeric and hexidecimal displays for use in high reliability applications. The displays feature
The 4N52 is the same as the 4N51, but the decimal point is located on the left side of the device.
The 4N53 is an over range device which displays “+1” and a right-hand decimal point. This display is typically driven using external
switching transistors.
The 4N54 is a hexidecimal display which decodes positive BCD logic into 16 characters “0-9, A-F”. An input is provided to blank the
display (all LED’s off) without losing the contents of the memory.

NOTES: 1. Whenever electrical/optical tests are not required as endpoints, electrical rejects may be used.
2. The LTPD applies to the number of leads inspected, except in no case shall less than 3 displays be used to provide the number of leads required.
3. Initial conditioning should be a 15” bend inward one cycle.
4. Limits and conditions are per the electrical/optical characteristics.
5. Burn-in for the over range shall use Condition B at a nominal I
6. Solderability samples shall not be used.
7. Visual requirements shall be as specified in MIL-PRF-883, Methods 1010 or 1011.
8. Displays may be selected prior to seal.
9. If a given inspection lot, undergoing Group B inspection, has been selected to satisfy the Group C inspection requirements, the 340 hour life tests may
be continued on test to 1000 hours in order to satisfy the Group C Life Test requirements. In such cases, either the 340 hour endpoint measurements
shall be made a basis for Group B lot acceptance or the 1000 hour endpoint measurement shall be used as the basis for both Group B and Group C
acceptance.
10. MIL-PRF-883 test method applies.
