The CD74HC367E is a 74HC-series non-inverting buffer with 3-state outputs, packaged in a 16-pin DIP that fits through-hole boards and breadboards alike.
Rated for the full military temperature span, this buffer is at home in avionics, satellite payloads, downhole instrumentation, or any outdoor telecom cabinet that sees -40°C winters and +85°C afternoons. The 7.8 mA source and sink capability per output is modest — enough to drive a few CMOS inputs or a short PCB trace — but the real value here is the temperature endurance. If your design lives inside a sealed enclosure near a motor drive or an engine bay, this part won't be the weak link.
Package and mounting
The CD74HC367E contains two independent buffer elements: one with 2 bits and the other with 4 bits (hex). That 2+4 split is unusual — most hex buffers give you six identical channels. Here, you get a 2-bit section and a 4-bit section, each with its own 3-state enable. Handy when you need to gate a 4-bit data bus and a separate 2-bit control bus from the same package, or when you're repairing a board where the original designer used that exact pinout. The 3-state outputs let you share a bus line without contention — just float the outputs when that section is not selected.
Lifecycle and sourcing
This is a current-production part from Texas Instruments, available through the usual distribution channels.
