DC4-12V Seven-segment Decoding Display Module

Description CD4511 is a commonly used seven segment display decoding driver In addition to the seven segment decoding circuit it also has a latch circuit and an output driver It has the characteristics of large output current up to 25MA drive current and can directly drive LED digital The tube CD4511 has 4 input terminals ABCD and 7 output terminals A G it also has input BCD code latch terminal LE lamp test LT extinguishing control terminal BI Among them ABCD is the BCD code input A is the low bit the input state can be controlled through S1 S4 when the corresponding switch is disconnected remove the short circuit cap the input is low level 0 when the corresponding switch is closed Put on the short circuit cap the input is high level ì LT is the light test terminal When the level is high the display will display normally When the level is low the display will always display the digital 8 and each segment will be lit to check whether the display is faulty This function can be performed through 55 test BI is the blanking function terminal when it is low it makes all 12345679101112131415 A A BB CCD DEFG LTBI LEIC1 CD4511 R9 1K R10 1K R11 1K R12 1K R13 1K R14 1K R15 1K A BC D E F G DP ABC DEFGDP COM DS11R3K2K2 S2 S1 LED R1 LED3 LED4 GNDR51KR61KR71K S7 S6 S5 VCC VCC VCC GND GND 12 JP1 C147UF GND R81KLED5GND 816 All strokes are blanked When displaying normally the BI terminal should add a high level and this function can be tested through 56
