TO99-8 Orange 7 segment LED display (CA)

Schematic , Counting

    The 1764 series of 7 segment LED displays are packaged in TO99-8 metal cans (TO5-8) and can be supplied in either common anode or common cathode configurations. Each segment consists of two 0201 high efficiency LEDs connected in series with a max current of 20mA however the typical segment drive current is much lower, per the table below. These displays have filters of the same color to improve contrast with the white display exhibiting the highest contrast.  All are very readable even when used under high ambient lighting conditions.
