Here’s a detailed explanation of the pin functions and the entire pinout description, including frequently asked questions (FAQs) about the CD4049UBDR.
Pin Function Specifications (CD4049UBDR, SOIC-16)
Pin Number Pin Name Pin Description 1 A1 Input of the first inverter (Inverting input) 2 Y1 Output of the first inverter (Inverted output) 3 A2 Input of the second inverter (Inverting input) 4 Y2 Output of the second inverter (Inverted output) 5 A3 Input of the third inverter (Inverting input) 6 Y3 Output of the third inverter (Inverted output) 7 A4 Input of the fourth inverter (Inverting input) 8 Y4 Output of the fourth inverter (Inverted output) 9 A5 Input of the fifth inverter (Inverting input) 10 Y5 Output of the fifth inverter (Inverted output) 11 A6 Input of the sixth inverter (Inverting input) 12 Y6 Output of the sixth inverter (Inverted output) 13 VSS Ground (0V) pin 14 VDD Supply voltage pin (Typically +5V or +3.3V) 15 NC No Connection (This pin is not connected internally) 16 NC No Connection (This pin is not connected internally)Important Notes:
VDD (Pin 14) is the Power supply pin that should be connected to the positive supply voltage (e.g., +5V or +3.3V). VSS (Pin 13) is the ground pin, connected to 0V. NC (Pins 15 and 16) are typically unused, meaning they do not have any internal connections and can be left floating. The A1 to A6 are input pins for the six inverters, and Y1 to Y6 are the corresponding inverted outputs.Circuit Principle
The CD4049UBDR is a hex buffer inverter. The principle is that the logic state of the input (A) is inverted at the output (Y). For example, if A1 = 1, then Y1 = 0. This device is used for logical operations and can be employed in applications where signal inversion is required. It uses bipolar junction transistor (BJT) technology to implement the inverters.
