7 Segment Led Display (Common Cathode) 7 Segment Led Display (Common Cathode), is a form of an electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. In a common cathode display, all of the LED segment cathode connections are connected to logic "0" or ground. Individual segments are illuminated by applying a "HIGH" or logic "1" signal to the individual Anode terminals via a current limiting resistor (a-g).

Get 0.96” OLED Display Module – High-Contrast Blue Screen Common Cathode Configuration Common Cathode 7 Segment Display Truth Table In a common cathode 7 segment display, all the cathodes of the LEDs are linked together. Each LED is accompanied by a current-limiting resistor connected between it and the +VCC. In this configuration, to activate a specific LED, it is connected to +5V. Thus, by connecting inputs a to g to VCC, digits ranging from 0 to 9 can be displayed. For instance, to display the digit 3, LEDs a, b, c, d, and g will emit light, while the remaining LEDs will remain inactive. Consequently, the illuminated LEDs will take the form of the digit 3.

74169 IC The 74169 is a digital logic IC that belongs to the 74xx series of integrated circuits. It is a 4-bit binary counter with a synchronous reset, meaning that the counter can be reset to zero at any time using a reset signal. The 74169 has four output lines, one for each bit in the counter, and it increments the count by one each time it receives a pulse on its clock input. It is commonly used in applications where a counter is needed, such as in timing circuits and frequency dividers. check out : 7448 IC Applications: Timing circuits Frequency dividers Pulse generation Digital clocks Automation systems Data acquisition systems check out : CD4028 - BCD to Decimal Decoder IC

74238 IC The 74HC Series 74HC238 decodes three binary weighted address inputs (A0, A1, and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1 and E2 and E3). Every output will be LOW unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four '238 ICs and one inverter. The 74238 IC can be used as an eight-output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. Inputs include clamp diodes. This enables the use of current-limiting resistors to interface inputs to voltages in excess of VCC. Pinout: Pinout of 74238 IC

7448 IC The 7448 is a digital logic IC that belongs to the 74xx series of integrated circuits. It is a BCD-to-7-segment decoder, which means that it can convert a binary-coded decimal (BCD) input into a pattern of signals that can be used to drive a 7-segment display. The 7448 has four BCD inputs and seven output lines, one for each segment of the 7-segment display. It also has an active-low output line for a decimal point. The 7448 is widely used in applications where a 7-segment display is used to display numerical information. check out : 74169 IC Applications: Digital clocks Digital thermometers Counters Process control displays Data acquisition systems Digital voltmeters
