Devices included in this entry:

Hewlett-Packard 5082-7340 red intelligent LED display (8-pin red epoxy DIP)
Hewlett-Packard 5082-7359 red intelligent LED display (8-pin glass-on-ceramic DIP)
Hewlett-Packard HDSP-0962 green intelligent LED display (8-pin glass-on-ceramic DIP; pictured in thumbnail)

The 5082-7300 and its descendants are some of the most popular intelligent LED displays ever produced. First introduced in 1972 as a lower cost replacement for the 5082-7000, the 7300 makes use of a smaller package and false-bitmapped 4×7 array, which reduces the number of LED dies needed for each device. Each display has an integrated BCD decoder that accepts 8421 BCD logic, as well as a built in latch. Initially this display was made in 3 different versions with different capabilities, including the 5082-7340, which could display hexadecimal characters. HP also produced the 5082-7304, an overflow indicator which contained no logic but was visually compatible with other displays in this series. Ironically, the 5082-7304 is much harder to find than the other displays in this family, despite its limited utility.

Hewlett Packard also produced a number of military grade derivatives of the 7300, which were encased in hermetic glass and ceramic packages. Two such examples are the 5082-7359, a red LED device, and the HDSP-0962, which makes use of green LEDs.
