Multiplexed display 7 segments Double common cathode
share this product
Description
Display 7 segments Red double multiplexed common cathode, used for the representation of numbers in many electronic devices, due largely to its simplicity.
It is normally used with a BCD encoder, which can be the 74LS47 integrated circuit that activates a single pin of the encoder input, activates the corresponding outputs by showing the desired number.
Main features:
- Typical operating voltage: 5V with the use of resistors from 120 Ω to 330Ω
- Consumption current per segment: 20 mA Total consumption per digit: Since we have 8 segments in the case where we show the number 8 together with the decimal point, the consumption will be 8 x 20 = 160mA
- Polarity: Common anode
- Color: Red Digits: 2
- 2 digits with decimal point on the right side
