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.
