0.56-inch 1-Digit Red LED Display Product Overview
The 0.56-inch 1-Digit Red LED Display is a 0.56-inch (14.2mm character height) 1-digit 7-segment LED display, featuring red emitting chips and available in both common cathode (5161AS / 5611AS) and common anode (5161BS / 5611BS) polarities. The 0.56-inch 1-Digit Red LED Display comes in a standard 10-pin package with outer dimensions of 19.0×12.6×8.0mm, capable of displaying digits 0-9 and some letters, widely used in various electronic devices requiring digital display.

0.56-inch 1-Digit Red LED Display Key Features
The 0.56-inch 1-Digit Red LED Display is a 1-digit 7-segment unit (with decimal point, total 8 segments) with a character height of 0.56 inches (14.2mm). Emitting color of the 0.56-inch 1-Digit Red LED Display is red with a peak wavelength of 640nm. Typical forward voltage of the 0.56-inch 1-Digit Red LED Display is 1.8V to 2V with recommended operating current of 20mA. The 0.56-inch 1-Digit Red LED Display is available in both common cathode (CC) and common anode (CA) polarities: 5161AS/5611AS are common cathode (common pins are 3 and 8); 5161BS/5611BS are common anode. Standard 10-pin package of the 0.56-inch 1-Digit Red LED Display has outer dimensions of 19.0×12.6×8.0mm. Luminous intensity of the 0.56-inch 1-Digit Red LED Display is approximately 25mcd. Operating temperature range of the 0.56-inch 1-Digit Red LED Display is -40℃ to +85℃.

Common Cathode vs Common Anode
For the 0.56-inch 1-Digit Red LED Display, common cathode models (5161AS / 5611AS) have all LED segment cathodes connected together (common pin connected to ground), requiring a high level signal to each segment anode to light up (high-level drive); common anode models of the 0.56-inch 1-Digit Red LED Display (5161BS / 5611BS) have all segment anodes connected together (common pin connected to power), requiring the cathodes to be pulled low to emit light (low-level drive). The two polarities of the 0.56-inch 1-Digit Red LED Display have opposite logic and different driving methods. Common cathode types are suitable for NPN transistors or open-drain output ICs (such as 74HC595 + BC847), while common anode types require PNP or high-side drivers (such as TPIC6B595).
