The numeric indicator decodes positive 82 BCD logic inputs into characters -9, a sign, a test pattern, and four blanks in the invalid BCD states. The unit employs a right-hand decimal point.

In place of the decimal point an input is provided for blanking the display (all EDs off), without losing the contents of the memory. Applications include terminals and computer systems using the base- 6 character set. The is a (± ) overrange display including a righthand decimal point. Applications Typical applications include pointof-sale terminals, instrumentation, and computer systems. Absolute Maximum Ratings Description Symbol Min. Max.
