Each of the six elements buffers a single bit with a push-pull output stage, so it can both source and sink current without needing an external pull-up. The supply range spans 2V to 6V, which lets it bridge 3.3V and 5V logic domains in mixed-voltage systems. Output drive is rated at 5.2mA for both high and low states, enough to drive a few CMOS inputs or a short trace without a line driver. ## Package and footprint Housed in a 16-SOIC package with a 0.209-inch (5.30 mm) body width, the CD74HC4049NS uses a standard surface-mount footprint that matches common SOIC-16 land patterns. It ships in tube form, which is typical for through-hole and SOIC parts ordered in moderate quantities.","metaTitle":"CD74HC4049NS 74HC Hex Inverting Buffer, 2V-6V, 16-SOIC","metaDescription":"CD74HC4049NS hex inverting buffer from the 74HC series. 2V to 6V supply, push-pull outputs, 5.2mA drive, -55°C to 125°C.

The base CD74HC4049 typically comes in a DIP or other package; the NS suffix indicates the SOIC-16 package with a 5.30 mm body width."},{"question":"Can CD74HC4049NS be used as a level shifter?","answer":"Yes, because the 74HC family accepts inputs from 2V to 6V while operating from a separate supply rail, the CD74HC4049NS can translate logic levels between 3.3V and 5V domains. The push-pull output drives rail-to-rail, so it works for unidirectional level shifting at moderate speeds."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC4049NS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC4049NS when reusing this data.
