74HC hex buffer with 3-state outputs in a breadboard-friendly DIP
The MM74HC367N is a Texas Instruments 74HC-series hex non-inverting buffer with 3-state outputs, packaged in a 16-pin DIP (0.300", 7.62mm) through-hole package — the same footprint that fits standard breadboards and perfboards, making it a go-to for hobbyist and bench-prototyping builds. It operates from a 2V to 6V supply over the industrial temperature range of -40°C to 85°C, with symmetrical output drive of 7.8 mA source and sink per channel — enough to drive LED indicators or the inputs of a following logic stage without a separate line driver.
Logic architecture and output control
The device contains two buffer elements: one with 2 bits per element and one with 4 bits per element, giving a total of six non-inverting channels. The 3-state outputs let you float the bus when the output-enable pins are inactive — useful for shared data lines where multiple drivers need to yield the bus without contention.
Lifecycle and compliance reality
Note the RoHS compliance status: this part is marked RoHS non-compliant. If your BOM requires RoHS-10 or REACH conformity, factor in the exemption or look for a lead-free variant in the same 74HC family — the standard 74HC logic series includes both tin-lead and RoHS-compliant options depending on the suffix.
