What are the key features of CD74HC4049PWT?
- 6 independent inverting buffer channels with CMOS-to-TTL level translation for seamless mixed-logic interfacing
- Wide 2 V to 6 V supply range accommodates both 3.3 V CMOS and 5 V TTL systems without external components
- 16-pin TSSOP package with 50 pF load rating enables high-density placement on compact PCBs
What is CD74HC4049PWT used for?
The CD74HC4049PWT is commonly used as a level translator and signal inverter in mixed-voltage digital systems, bridging 3.3 V CMOS logic outputs to 5 V TTL-compatible inputs in microcontroller interfaces and FPGA peripheral circuits. Its 6 independent channels allow simultaneous translation of multiple signal lines in data buses, I/O expanders, and industrial sensor interfaces. It also serves as a low-power inverting buffer in portable instruments where the 2 V minimum supply supports battery-operated designs.

Frequently Asked Questions
How does the CD74HC4049PWT perform CMOS-to-TTL level translation across its 2 V to 6 V supply range?
The CD74HC4049PWT's input stage accepts CMOS voltage levels and its output is clamped to meet TTL VIH/VIL thresholds, allowing direct connection between a 3.3 V CMOS source and a 5 V TTL destination without external resistors. The device operates from 2 V to 6 V, covering both logic families in a single 16-pin TSSOP package with 50 pF load drive capability and 4 mA sink current per channel.
For a compact motor-driver interface board, how many signal lines can the CD74HC4049PWT invert and translate simultaneously?
The CD74HC4049PWT provides 6 independent inverting buffer channels in a single 16-pin TSSOP package, enabling simultaneous inversion and level translation of up to 6 digital control lines. This is useful in motor-driver gate-drive boards where direction, enable, and fault signals from a 3.3 V microcontroller must be adapted to 5 V logic inputs, all with a 50 pF load rating per channel.
When is the CD74HC4049PWT preferred over a non-inverting buffer such as the CD74HC4050 for signal conditioning?
The CD74HC4049PWT is chosen over a non-inverting buffer when the downstream circuit requires active-low polarity from an active-high source, or when a logic inversion is needed to correct signal polarity in cascaded digital stages. Its 2 V to 6 V supply range and 50 pF load capacitance rating match the CD74HC4050 electrically, so the choice is purely based on whether the application needs inversion across 6 channels in the compact TSSOP-16 footprint.
