- Package: 8-Pin Plastic DIP (Through-Hole, 0.300-inch row spacing)
Applications
- Replacing failed bus transceivers on industrial PLCs, CNC controllers, and building automation panels.
- Interfacing microcontrollers with long-distance differential serial buses and DMX512 lighting networks.
- Prototyping noise-immune multi-drop sensor networks on breadboards and through-hole PCBs.
Frequently Asked Questions
What is the pin configuration and package style?
This is a standard through-hole 8-pin plastic DIP (PDIP-8) with 0.300-inch lead spacing.
What supply voltage does the MAX485CPA require?
It operates from a single 5V DC power source (4.75V to 5.25V range).
Why buy this MAX485CPA from PartsMine rather than an untested multi-part lot?
You receive the specific, photographed component ready for your repair or build without buying unnecessary surplus volume. Shipping is a flat $8, orders over $28 ship free, and orders leave our Idaho warehouse the same or next business day.
Long serial lines and noisy industrial environments still run on proven differential silicon. Drop this into your socket and get your bus communicating cleanly again.
