What are the key features of CD74HC4049M?
- 6 independent inverting CMOS buffer channels in a single 16-pin SOIC package for signal inversion and logic level shifting
- Wide 2 V to 6 V operating supply range enables direct interfacing between different logic families including TTL, CMOS, and NMOS
- HC-family high-speed CMOS technology delivers fast switching speed with low quiescent current for power-sensitive portable designs
What is CD74HC4049M used for?
The CD74HC4049M is widely used as a hex logic inverter and voltage-level translator in systems that need to interface 5 V logic outputs with 3.3 V or lower-voltage logic inputs. Six independent inverting channels allow simultaneous signal conditioning of multiple lines, making it useful in bus interface circuits, microcontroller peripheral adapters, and display driver signal conditioning. Its SOIC-16 package suits automated SMT assembly in industrial control, consumer electronics, and communication equipment boards.

Frequently Asked Questions
How many inverting channels does the CD74HC4049M provide and what supply voltage range does it support?
The CD74HC4049M integrates 6 independent inverting buffer channels operating from a 2 V to 6 V supply, allowing it to invert and level-shift up to 6 logic signals simultaneously without additional components in 3.3 V to 5 V mixed-voltage systems.
Can the CD74HC4049M translate logic levels between a 5 V microcontroller and a 3.3 V peripheral?
Yes, the CD74HC4049M accepts input signals above its logic supply voltage on its inverting inputs (the input clamp diode is absent on the 4049 topology), so a 5 V logic output can drive an input while the CD74HC4049M's supply is at 3.3 V, producing inverted 3.3 V outputs suitable for driving lower-voltage peripherals.
What package does the CD74HC4049M use and how does it compare to the DIP variant for production boards?
The CD74HC4049M is supplied in a 16-pin SOIC package with 1.27 mm lead pitch, which occupies significantly less PCB area than the 16-pin DIP variant and is compatible with automated surface-mount reflow soldering processes used in high-volume production.
When would a designer choose the CD74HC4049M over the non-inverting CD74HC4050 buffer?
A designer selects the CD74HC4049M when an inverted logic polarity is needed — for example, converting an active-high enable signal to active-low chip-select, or driving active-low LED anodes — whereas the CD74HC4050 is chosen when signal polarity must be preserved across a level-shifting boundary.
