DIS1417: A Modern Replacement for the Classic TIL311 Hexadecimal Display

The DIS1417 is a modern, reliable replacement for the vintage TIL311 hexadecimal LED display module, once produced by Texas Instruments. If you're restoring retro computing equipment, building digital counters, or need a self-contained display with onboard logic, the DIS1417 offers a compact, functionally equivalent alternative with easier sourcing and modern compatibility. 🕰️ Background: The TIL311 Legacy First introduced in the early 1970s, the TIL311 was a popular hexadecimal display module featuring a bright red 7-segment LED, an onboard BCD (Binary-Coded Decimal) decoder, latching capability, and constant-current drivers. It became a staple in test equipment, early microcomputers, calculators, and educational electronics due to its simplicity—no need for external decoders or transistors. Unfortunately, the TIL311 has long been discontinued, making it expensive and difficult to find. Enthusiasts and engineers needing replacements have had to rely on NOS (new old stock), ...
