The series includes a left hand and a right hand decimal point nu- meric display as well as a polarity and overflow indicator, The large 7.62mm (0.3 in.) high character size generates a bright, continuously uniform seven segment display. Designed for viewing distances of up to 10 feet, these single digit displays provide a high contrast ratio and a wide viewing angle, The 5082-7730 series devices utilize a standard 7.62mm (0.3 in.) dual-in-line package configuration that permits mounting on PC boards or in standard IC sockets. Requiring a low forward voltage, these displays are inherently IC compatible, allowing for easy inte- gration into electronic instrumentation, point of sale terminals, TVs, radios, and digital clocks.

As depicted in Figure 4, character encoding on the 7730 and the 7731 can be performed by commercially available BCD-7 segment decoder/driver circuits. Through the use of strobing techniques, only one decoder/driver is required to drive a display containing ua to 16 characters as outlined in Figure 6. When each character in the display is iNuminated in sequence, at a minimum of 100 times per second, flicker-free characters are formed. Under average current drive conditions of 10mA/segment, the display is easily readable to distances of ten feet and will retain good contrast under relatively high ambient lighting conditions. The 5082-7730 series devices are constructed utilizing a lead frame in a standard DIP package. The individual packages OATA ENTRY SEVEN SEGMENT DECODER SEGMENT BUFFERS DIGIT SCANNER DIGIT AND BUFFERS cLocK may be close-packed at 10.16mm (.4 in.) centers on a PC board. Also, the larger character height allows other charac- ter spacing options when desired. The lead frame has an inte- gral seating plane which will hold the package approximate- ly 1.52mm (.060 in.} above the PC board during standard soldering and flux removal operation. To optimize device performance, new materials are used that are limitecl to cer- tain solvent materials for flux removal. It is recommended that only Freon TF, Freon TE, (for Freons, up to 2 min. max. at boiling temp.), Isoproponal, Ethanol, Genesolv DI- 15, Genesolv DE-15, or water be used for cleaning operations. To improve display contrast, the entire front surface of the display, except for emitting areas, is finished in a uniform flat black. Additional filters may be incorporated, if desired, to further lower the ambient reflectance and improve dis- play contrast. See Hewlett Packard Application Note 964 for further information regarding the contrast enhancement. HP 5082-7730 HP 5082-7730 HP 5082. 7731 HP 5082-7731 Figure 6.
