Devices included in this entry:

Hewlett-Packard 5082-7300 (8-pin epoxy DIP)
Hewlett-Packard HDSP-0781TXV (8-pin glass-on-ceramic DIP)
Hewlett-Packard 5082-7340 (8-pin epoxy DIP)
Hewlett-Packard 5082-7359 (8-pin glass-on-ceramic DIP)
Hewlett-Packard HDSP-0962 (8-pin glass-on-ceramic DIP; pictured in thumbnail)


The Hewlett-Packard 5082-7300 is the Cadillac of early single-digit intelligent LED displays, with an integral hexadecimal decoder, positive 8-4-2-1 logic input and memory, all in a tiny 8-pin DIP. The 5082-7300 is significantly smaller than the benchmark TIL311.

5082-73xx devices are available in two basic types: decimal and hexadecimal display. The 5082-7300 displays digits 0-9 plus a decimal point, while the 5082-7340 displays characters 0-F and includes a blanking function.

5082-73xx devices have a false bitmap display, which gives the appearance of a true bitmap character, but only includes the pixel elements required to make up the display's limited character set. Unlike true bitmap character displays, which usually have a 5x7 matrix, 5082-73xx has a 4x7 matrix, with the elements spaced further apart horizontally than vertically.

The 5082-7300 and 5082-7340 have many pin-compatible descendants in various colors and construction styles. The HDSP-0781TXV is a ruggedized variant of the 5082-7300, designed for military use. The 5082-7359 and HDSP-0962 are variants of the 5082-7340, designed for industrial applications.

Hewlett-Packard 5082-7340 intelligent hexadecimal display with blanking.


Hewlett-Packard 5082-7359 intelligent display. The 5082-7359 is electrically identical to the 5082-7340 pictured above, but replaces the standard red epoxy package with a ruggedized glass-on-ceramic DIP, designed for operation in harsh environments.


Hewlett-Packard HDSP-0962 intelligent display. The HDSP-0962 is extremely similar to the 5082-7359, but is equipped with green LED dies instead of red like the 5082-7359. The glass-on-ceramic enclosure allows for a range of display colors, a design versatility not permitted with the older red epoxy construction of the 5082-7340.
