Frequently Asked Questions
What is the supply voltage range for the CD74HC4049E?
The CD74HC4049E operates over a supply voltage (VCC) range of 2V to 6V, making it compatible with both 3.3V CMOS systems and 5V TTL/CMOS systems. This wide range enables seamless use in mixed-voltage designs without additional regulation.
What is the CD74HC4049E used for?
The CD74HC4049E is a hex inverting buffer primarily used for logic signal inversion and CMOS-to-TTL level conversion. Typical applications include bus driving, signal conditioning, interface circuits between microcontrollers and legacy TTL logic, and general-purpose inverting buffer tasks in digital systems.
How many inverting channels does the CD74HC4049E provide?
The CD74HC4049E provides 6 independent inverting buffer channels in a single 16-pin DIP package. Each channel can operate independently, allowing designers to use one or all channels as needed within the same IC to minimize board space and component count.
What package does the CD74HC4049E come in?
The CD74HC4049E is available in a PDIP-16 (plastic dual in-line, 16-pin) through-hole package. This traditional package is well-suited for prototyping, hobbyist projects, and applications where hand-soldering or socketed components are preferred.
What are alternatives to the CD74HC4049E?
Common alternatives to the CD74HC4049E include the 74HC4049 from other manufacturers such as NXP and ON Semiconductor, as well as the CD74HCT4049E (TTL-compatible inputs), 74HC04 (6-channel hex inverter), and 74AHCT04 for higher-speed applications. Selection depends on supply voltage, speed, and package requirements.
