Product details

30Mbps differential bus transceiver in a through-hole DIP

The ADM1485JNZ is a half-duplex RS422/RS485 transceiver from Analog Devices that pushes 30 Mbps across a differential pair — fast enough for high-speed fieldbus backbones or multi-drop sensor arrays where the bus timing budget is tight.

Through-hole package and board-fit reality

Housed in an 8-pin DIP (0.300-inch body width, 7.62 mm pitch), the ADM1485JNZ is a through-hole part — it goes into a socket or solders directly into plated through-holes on a standard 0.100-inch grid prototype board or production PCB. The DIP footprint is rework-friendly: a hand-soldering iron or desoldering station handles it without hot-air gear, which matters for a repair bench or a low-volume build where surface-mount reflow is not available.

Frequently asked questions

What is the closest functional alternative to ADM1485JNZ?

The surface-mount sibling ADM1485JRZ shares the same 30 Mbps data rate, half-duplex protocol, and 70 mV hysteresis — the only difference is the package (SOIC-8 vs DIP-8), so a board spin is needed to swap between them.

Will ADM1485JNZ drop into a board designed for ADM1485JRZ?

No — the ADM1485JNZ is through-hole DIP-8, while the ADM1485JRZ is surface-mount SOIC-8. The pin functions are identical, but the footprint and assembly process are completely different.
