Applications
The CD74HC4050NSRG4 is commonly used as a level translator between 5-V CMOS logic and TTL-compatible devices, or as a hex buffer for signal isolation and fan-out in digital bus interfaces. Its six independent non-inverting channels make it ideal for translating address, data, or control lines in legacy 5-V digital systems interfacing with 3.3-V or TTL-level peripherals. The device is also used in interface boards, industrial PLCs, and microcontroller expansion modules where logic signal buffering is required.

Frequently Asked Questions
What is the CD74HC4050NSRG4 and what logic function does it perform?
The CD74HC4050NSRG4 is a hex non-inverting buffer from Texas Instruments' HC high-speed CMOS family. It contains 6 independent single-input, single-output non-inverting buffer channels that pass logic signals without inversion while providing buffering, isolation, and CMOS-to-TTL level translation. Each channel supports a 50-pF load capacitance and 4-mA output sink current.
Can the CD74HC4050NSRG4 translate between different logic voltage levels?
Yes, the CD74HC4050NSRG4 includes an additional feature described as a CMOS-to-TTL level translator. This means it can accept high-level CMOS input signals from 5-V systems and produce outputs compatible with TTL logic thresholds. This makes it useful for interfacing 5-V CMOS logic with TTL-level or 3.3-V LVCMOS devices without external resistor networks.
How many channels does the CD74HC4050NSRG4 have and what package does it use?
The CD74HC4050NSRG4 provides 6 independent buffer channels (Number of Functions: 6), each with one input and one non-inverting output. The device is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) surface-mount package with a JESD e4 moisture sensitivity rating, and is fully RoHS-compliant and lead-free.
What is the output drive capability of the CD74HC4050NSRG4?
Each output channel of the CD74HC4050NSRG4 can sink a maximum of 4-mA (Max I(ol) = 0.004 A) and drive a load capacitance of up to 50-pF. These parameters are typical for the HC CMOS logic family and support connection to standard CMOS or TTL gate inputs as well as low-current indicator loads in digital interface applications.
What are alternatives or related parts to the CD74HC4050NSRG4?
The CD74HC4050 belongs to Texas Instruments' HC/UH high-speed CMOS family. Related parts include the CD74HCT4050 for direct TTL supply voltage operation, the 74HC4049 hex inverting buffer for applications requiring signal inversion, and the SN74HC244 for higher-drive 8-channel buffering with tri-state outputs. For 3.3-V applications, consider the 74LVC family equivalents such as SN74LVC1G07 or SN74LVC8T245.
