Applications
The CD74HC4050PWR is designed for CMOS-to-TTL level translation in mixed-voltage digital systems where signals from 5V or higher CMOS logic must interface with 3.3V or TTL-level inputs without damaging the receiving device. It is commonly used in microcontroller I/O expansion, FPGA interface boards, and legacy system integration projects where different logic families must coexist. The device also serves as a six-channel buffer for signal fanout and drive reinforcement in bus-loaded digital circuits.

Frequently Asked Questions
What is the primary function of the CD74HC4050PWR?
The CD74HC4050PWR is a hex non-inverting buffer primarily used as a CMOS-to-TTL level translator. It accepts input signals that may exceed the supply voltage, making it ideal for translating higher-voltage CMOS logic (such as 5V signals) down to TTL-compatible levels when powered at a lower supply voltage, without inverting the signal polarity.
Can the CD74HC4050PWR inputs exceed the supply voltage?
Yes, a key feature of the CD74HC4050PWR is that its inputs are designed to tolerate voltages higher than the VCC supply. This makes it possible to directly connect 5V CMOS outputs to the device inputs while operating the device at 3.3V supply, achieving downward voltage level translation without requiring additional protection circuitry or level-shift components.
How many buffer channels does the CD74HC4050PWR provide?
The CD74HC4050PWR provides six independent non-inverting buffer channels in a single package. Each channel can be used independently, allowing the device to buffer or translate up to six separate signal lines simultaneously. This makes it efficient for multi-line bus interfaces, I/O port buffering, and parallel data path translation between mixed-voltage logic systems.
What package is the CD74HC4050PWR available in?
The CD74HC4050PWR comes in a 16-pin TSSOP package (JESD-30 code R-PDSO-G16), which is a surface-mount package with a very compact 4.4mm body width. The TSSOP format is well-suited for high-density PCB designs and is compatible with automated SMT assembly, making it a popular choice for modern compact electronic products.
What are typical use cases for the CD74HC4050PWR?
Typical use cases include bridging 5V legacy CMOS logic outputs to 3.3V TTL inputs in mixed-voltage microcontroller designs, buffering GPIO signals for increased drive strength and fanout in digital interfaces, and translating I2C, SPI, or GPIO bus signals between subsystems operating at different CMOS voltage standards. It is also used in FPGA prototyping boards and signal conditioning circuits for test and measurement applications.
