Product details

SSOP-16 footprint — rework and layout notes

Housed in a 16-SSOP package with a 0.209-inch body width and 5.30 mm footprint, this is a fine-pitch surface-mount device. Standard reflow profiles for SSOP apply; no special bake is required if the moisture barrier bag is intact. The 5.2 mA per-channel output drive is typical for 74HC-family bus buffering — adequate for driving a few CMOS inputs or short PCB traces, but not for heavy loads like relays or long cables.

Six inverting buffers — what the logic type means

This is a hex inverting buffer with push-pull outputs (not open-drain). Each of the six elements handles one bit. The inverting function means the output is the logical complement of the input — useful for signal polarity inversion, clock shaping, or driving active-low inputs.

Frequently asked questions

Can 74HC4049DB be used as a drop-in replacement for CD4049?

The CD4049 is a 4000-series CMOS inverting buffer with a wider supply range (3V to 15V) and lower drive current. The 74HC4049DB is a high-speed CMOS (74HC) variant with a 2V to 6V supply and 5.2 mA push-pull outputs. While both are hex inverting buffers, the supply voltage and drive capability differ — verify the system's rail voltage and load requirements before substituting.
