Texas Instruments TIL360 Multi-Digit Calculator LED Display

• Features

Texas Instruments introduced the TIL360 Multi-Digit Calculator Numeric Seven-Segment LED Displays with Right-Hand Decimals already in Fall 1971 together with the announcement of the TMS1802 (later renamed to TMS0102) single-chip calculator circuit.

These Multi-Digit displays are intended for use under pulsed conditions by enabling the common cathode of each digit sequentially and enabling the desired segment anode and/or right-hand decimal point anode in phase with the character enabling pulse. The pulse rate is kept high enough so that light from each character appears to the eye to be constant. Two or more of these devices may be stacked end-to-end to provide additional characters with constant spacing between characters. When additional characters are enabled by the same pulse sequence, the peak current in each segment or decimal may be increased to maintain the character brightness despite the lower duty cycle for each character.

• 0.1”/2.54 mm Characters
• Seven-Segment Digits with Right-Hand Decimals
• Continuous Uniform Segments
• Wide Viewing Angle
• Common-Cathode Configuration for Multiplex Applications
• 0.17”/4.3 mm Character Spacing with End-to-End Stacking of Devices

• Product Options

Texas Instruments provided various Multi-Digit displays that are variations of the TIL360, best known are the DIS40 and DIS95:

• The DIS40 uses for digit position #1 a special character E, forming the minus sign for negative numbers or C/E for error conditions.
   Digit position #2 is not used and no connection should be made to Pin 3
• The DIS95 doesn’t use digit positions #5 and #6 and no connections should be made to Pin 6 and Pin 11

Different combination of the TIL360 and its variations support various configurations of the TMS0100 family of single-chip calculator circuits:

• DIS40 + DIS95: Sign/Overflow + 8-digit display
• DIS40 + TIL360: Sign/Overflow + 10-digit display
• TIL360 + TIL360: Sign/Overflow + 8-digit Mantissa + Sign + 2-digit Exponent display

• Technology

The digit and decimal chips are mounted on a ceramic header which is then hermetically sealed with a glass cover. Character-to-character spacing is maintained when multiple displays are mounted end-to-end.

• Packaging

The TIL360 uses a 0.3” wide 16-pin Package with a 0.1” / 2.54 mm lead pitch.
