What are the key features of CD74HC4049EE4?
- Six independent inverting buffer channels enabling CMOS-to-TTL level translation without external pull-up resistors in mixed-logic systems
- High-speed HC/UH CMOS family operation offering significantly faster propagation delays than legacy 4000B series CMOS for demanding digital designs
- 4mA output sink current (IOL) per channel providing sufficient drive strength for TTL loads and LED indicators directly from the output
- RoHS-compliant 16-pin PDIP through-hole package with 50 pF load capacitance rating for breadboard prototyping and through-hole PCB assembly
What is CD74HC4049EE4 used for?
The CD74HC4049EE4 is primarily used for voltage level translation between 5V CMOS logic and TTL-level systems, allowing CMOS outputs to drive TTL inputs directly without external buffers. Its six inverting channels make it efficient for bus buffering, logic signal inversion, and driving multiple TTL loads in parallel from a single CMOS source. It is also used in clock signal distribution, display driver interfaces, and legacy 4000B-series CMOS replacement applications where higher speed and TTL compatibility are required.

Frequently Asked Questions
What is the CD74HC4049EE4 and how many channels does it have?
The CD74HC4049EE4 is a hex (6-channel) inverting buffer and CMOS-to-TTL level translator from Texas Instruments. It contains six independent inverter stages in one 16-pin PDIP package, making it a compact and economical solution for translating logic levels or inverting and buffering multiple digital signals simultaneously.
How does the CD74HC4049EE4 perform CMOS-to-TTL level translation?
The CD74HC4049EE4 accepts CMOS input voltage levels and produces TTL-compatible output levels with sufficient drive strength (4mA IOL) to directly interface with standard TTL logic gates. Unlike many HC-family devices, it can accept input voltages higher than VCC, making it particularly suited for translating 5V CMOS signals into 3.3V TTL-compatible logic in mixed-voltage digital systems.
What is the output drive capability of the CD74HC4049EE4?
Each inverter channel of the CD74HC4049EE4 can sink a maximum of 4mA (IOL) at its output. This is sufficient to drive standard TTL logic inputs, low-current LEDs (with appropriate series resistor), and typical CMOS loads rated at 50 pF capacitance, while maintaining valid TTL output voltage levels within the specification sheet limits.
What package does the CD74HC4049EE4 come in and is it RoHS compliant?
The CD74HC4049EE4 is packaged in a 16-pin PDIP (Plastic Dual Inline Package) through-hole format (JESD-30 code R-PDIP-T16). The E4 suffix confirms it is RoHS compliant and Pb-free, meeting international environmental regulations. Its through-hole format is ideal for hand assembly, prototyping on breadboards, and applications requiring mechanical durability.
What are typical applications for the CD74HC4049EE4?
Typical applications include CMOS-to-TTL level translation in mixed-logic PCB designs, logic signal inversion in control systems, bus buffering to extend fanout beyond what a single CMOS gate can drive, LED segment display drivers, clock signal buffering and distribution, and as a drop-in high-speed replacement for the slower CD4049B in existing designs requiring faster switching speeds.
