Product Overview
Archer catalog number 276-1656 provides a pair of vintage 0.4-inch (10.2 mm) 7-segment common anode red LED displays for breadboarding, bench repairs, and digital readouts. Distributed through Radio Shack and Tandy Corporation, each DIP-14 module features operable left and right decimal points and mounts easily into standard IC sockets.
Key Features
- Common anode circuit configuration with standard red emission
- 0.4-inch (10.2 mm) character height with left and right decimal points
- DIP-14 package footprint with 0.100-inch pin pitch and 0.300-inch row spacing
- 25 mA continuous forward current per segment or decimal point
- 400 mA peak forward current rating (pulse duration 10 microseconds or less)
- 50 mW power dissipation per segment at 25 degrees Celsius
- 6.0 V peak inverse voltage rating per segment
- Operating temperature range from -35 to +85 degrees Celsius
Applications
- Restoring readout segments in vintage Radio Shack digital clocks, frequency counters, and sensor meters
- Prototyping decimal counters and countdown timers on solderless breadboards
- Replacing damaged common anode LED displays in retro test equipment and hobby electronics projects
Frequently Asked Questions
Which pins provide the common anode connection?
Pins 3 and 14 are internally connected common anode terminals. Connecting positive DC supply voltage through your current-limiting resistors to either pin powers the display segments.
Can this display directly replace a common cathode display?
No. Common anode displays require an active-low sink driver or switching to ground to turn on segments. Common cathode displays require active-high source drive.
What socket footprint does this module fit?
The module uses a standard DIP-14 footprint with 0.100-inch pin spacing and 0.300-inch row width, fitting standard dual in-line IC sockets, wire-wrap sockets, and standard solderless breadboards.
There is an unmistakable warmth to classic red seven-segment displays that modern screens cannot replicate. Plug them into your breadboard and let those clean crimson digits do the talking.
