Working Principles

The CD4049UBDRG4 is a hex inverter/buffer IC that converts input logic signals into their inverted form. It operates on a wide supply voltage range of 3V to 18V, making it suitable for various applications. The CMOS technology used in this IC ensures low power consumption while providing high voltage tolerance.

Each of the six inverters within the CD4049UBDRG4 has an input pin and an output pin. When a logic HIGH signal is applied to the input pin, the corresponding output pin produces a logic LOW signal, and vice versa. This inversion of logic signals allows for signal conversion and buffering in digital circuits.

Detailed Application Field Plans

The CD4049UBDRG4 can be used in a variety of applications, including:

1. Logic level shifting
2. Signal inversion
3. Voltage level conversion
4. Buffering of digital signals
5. Oscillator circuits
6. Pulse shaping circuits
7. Waveform generation

Its high voltage tolerance and wide operating temperature range make it suitable for use in industrial, automotive, and consumer electronics applications.
