CD4049 - Hex Inverting Buffer/Converter IC

The CD4x Series CD4049 hex buffers are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. These devices feature logic-level conversion using only one supply voltage (VDD).

The input signal level can exceed the VDD supply voltage when these devices are used for logic-level conversions. These devices are intended for use as hex buffers, CMOS to DTL/TTL converters, or as CMOS current drivers, and at VDD=5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range.

ADDITIONAL RESOURCES

1.What is CD4049?

  • The CD4049 is a hex inverting buffer/converter, which means it has six NOT gates (inverters) and a higher sink current than most logic gates. It has 16 pins, two of which are disabled. Because it can accept a higher input voltage than its supplied VDD voltage, this chip is frequently used for level shifting.

2.What is a NOT gate/Inverter?

  • A NOT gate (or inverter) is a logic gate that produces the inverse of what it receives. As a result, a 1 (HIGH) on the input results in a 0 (LOW) on the output.

3.How to Use the CD4049 in a Circuit?

  • To use the CD4049 in a circuit, a power supply voltage of 3 to 20V is required. Connect the chip's VDD and GND pins to the power supply. You can now use any of the six inverters by connecting something to the input and output pins.
