It handles one driver and one receiver on a single differential bus, with a 50 mV receiver hysteresis for noise rejection on long cable runs.
Through-hole DIP — rework-friendly footprint
The 8-DIP (0.300 inch row spacing) package is a through-hole part. It sits in a standard 0.1 inch pitch socket or solders directly into plated through-holes. For a rework technician, this is about as forgiving as it gets — the part lifts cleanly with a desoldering station or even a manual solder sucker, and the pin 1 indicator is the molded notch at the DIP end. No hot-air profile needed, no moisture sensitivity level to track. The 8-PDIP supplier package code confirms the same 300-mil body.
Supply rail and bus voltage tolerance
The receiver input common-mode range and driver differential output are designed for RS-485 bus voltages; this is not an RS-232 part. The 1 Mbps data rate is the maximum specified; actual throughput depends on cable length, termination, and bus loading, but the transceiver itself is rated for that bit rate end-to-end.
