The displays feature 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). 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 blan...
