hexadecimal indicators with on-board decoder/driver
and memory provide 7.4 mm (0.29 inch) displays for
reliable, low-cost methods of displaying digital
information.
The 5082-7300 numeric indicator decodes positive
8421 BCD logic inputs into characters 0-9, a “–” sign, a
test pattern, and four blanks in the invalid BCD states.
The unit employs a right-hand decimal point.
Features
• Numeric 5082-7300/-73020-9, test state, minus sign,
blank states
– Decimal point: 7300 right hand d.p.
7302 left hand d.p.
• Hexadecimal 5082-73400-9, A-F, base 16 operation
blanking control, conserves power
– No decimal point
• DTL/TTL compatible
• Includes decoder/driver with 5-bit memory 8421
– Positive logic input
• 4 x 7 dot matrix array
– Shaped character, excellent readability
• Standard dual-in-line package including contrast filter
15.2 mm x 10.2 mm (0.6 inch x 0.4 inch)
• Categorized for luminous intensity
– Assures uniformity of light
– Output from unit to unit within a single category

2. UNLESS OTHERWISE SPECIFIED,
THE TOLERANCE ON ALL

3. DIGIT CENTER LINE IS ± 0.25 mm
(± 0.01 INCH) FROM PACKAGE
CENTER LINE.
The 5082-7302 is the same as the
5082-7300, except that the
decimal point is located on the
left-hand side of the digit.
The 5082-7340 hexadecimal
indicator decodes positive 8421
logic inputs into 16 states, 0-9 and
A-F. In place of the decimal point
an input is provided for blanking
the display (all LEDs off), without
losing the contents of the
memory. Applications include
terminals and computer systems
using the base-16 character set.
The 5082-7304 is a (±1) overrange
display including a right-hand
decimal point.
Applications
Typical applications include
point-of-sale terminals,
instrumentation, and computer
systems.
