Hewlett-Packard manufactured a number of early DIP single die LED displays for use in handheld calculators, designed to be mounted in larger linear arrays. The HP 5082-7433 is a three-digit, seven-segment red LED display, which is compatible with the Litronix DL3xx series shown above, as well as other similar displays. The -7433 is not intelligent; control must be furnished entirely with external driver circuitry.
The 5082-7415 is the five digit version of the -7433, and is otherwise electrically similar. The 5082-7432 is a strange two-digit version of the 7433, enclosed in a truncated 3-digit epoxy package with only two of the digits have dies installed. The -7412 is a similar device - a 12 pin, four digit package with only the three rightmost digits populated with dies.
