Key Features
- 6-element hex inverting buffer with push-pull outputs, providing up to 6 independent signal inversion channels in a single 16-pin PDIP package
- HC-family high-speed CMOS logic compatible with 2 V to 6 V supply rails for broad compatibility across 3.3 V and 5 V digital systems
- 1-bit per element push-pull output structure enabling direct load driving without additional current buffers on standard PCB signal lines
Applications
The CD74HC4049E-P2 is used as a signal inverter, level converter, and logic buffer in digital systems where multiple independent inversion channels are needed within a single device. Its hex structure makes it suitable for inverting address lines, control signals, and clock distribution in microprocessor and FPGA-based boards. Engineers use this device in bus interface circuits, LED drivers, and logic polarity correction applications where 6 buffered inverted outputs are required.

Frequently Asked Questions
How many inverter channels does the CD74HC4049E-P2 contain and how are they configured?
The CD74HC4049E-P2 contains 6 independent inverting buffer elements, each handling 1 bit with push-pull output drive. All 6 channels are housed in a single 16-pin PDIP package, making it a compact solution for multi-channel signal inversion requirements.
What supply voltage range does the CD74HC4049E-P2 support and is it compatible with 3.3 V systems?
The CD74HC4049E-P2 operates across a 2 V to 6 V supply range, making it compatible with both 3.3 V and 5 V logic systems. This wide voltage tolerance allows direct interface with modern low-voltage microcontrollers without additional translation components.
In what application scenarios would a designer prefer the CD74HC4049E-P2 over a single inverter?
When a design requires inverting 6 independent control or address signals, the CD74HC4049E-P2 replaces 6 discrete inverter gates with a single 16-pin PDIP IC. This integration reduces BOM line items and board area, simplifying assembly for designs such as address bus polarity correction and multi-channel enable logic.
Does the CD74HC4049E-P2 output structure support driving capacitive loads directly on PCB traces?
Yes, the push-pull output structure of the CD74HC4049E-P2 enables direct driving of standard PCB trace capacitances, typically up to 50 pF for HC-family devices, without needing external series resistors or additional buffer stages in typical digital logic applications.
