What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.\u003cbr\u003e \u003cbr\u003e This is an ultra-bright \u003cstrong\u003eRED \u003c\/strong\u003ecolour.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100mcd\u003c\/li\u003e\n\u003cli\u003e14.2mm (0.56\") digit height\u003c\/li\u003e\n\u003cli\u003eColor: red (630nm)\u003c\/li\u003e\n\u003cli\u003eCommon cathode display\u003c\/li\u003e\n\u003cli\u003eMaximum power dissipation per segment: 66mW\u003c\/li\u003e\n\u003cli\u003eMaximum pulse peak forward current per segment (1\/10th duty cycle, 0.1ms pulse width): 100mA\u003c\/li\u003e\n\u003cli\u003eMaximum forward current per segment: 20mA\u003c\/li\u003e\n\u003cli\u003eMaximum reverse voltage: 5V\u003c\/li\u003e\n\u003cli\u003eMaximum reverse current: 20µA\u003c\/li\u003e\n\u003cli\u003eTypical forward voltage: 2.1V at 20mA\u003c\/li\u003e\n\u003cli\u003eMaximum forward voltage: 2.5V at 20mA\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -30°C - +70°C\u003c\/li\u003e\n\u003cli\u003eTypical luminous intensity: 20mcd\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":53751180460395,"sku":"hyq1787257992327","price":1.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1268\/3883\/files\/four-digit-seven-segment-display---red_1.jpg?v=1787258001","url":"https:\/\/pickvirello.com\/products\/four-digit-seven-segment-display-red","provider":"Pickvirello","version":"1.0","type":"link"}
