The ADM2867E and the pending products within this family (on the datasheet, light blue at the top of each page and gray in text) are 5.7 kV rms signal and power isolated RS-485 transceivers. The devices pass radiated emissions testing to the EN55032 Class B standard with margin on a 2-layer printed circuit board (PCB) using two small external 0402 ferrites on isolated power and ground pins. The device features an integrated, low electromagnetic interference (EMI), isolated dc-to-dc converter, which eliminates the need for an external isolated power supply. The isolation barrier provides immunity to system level electromagnetic compatibility (EMC) standards. The family of isolator devices features ±12 kV contact and ±15 kV air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Z pins. The devices also features cable invert pins, allowing the user to quickly correct reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance.
Slew rate limited versions are available, which are optimized for low speed over long cable runs, and have a maximum data rate of 500 kbps. Half duplex and full duplex variants are available. The full duplex generics allow independent cable inversion of the driver and receiver for additional flexibility.
The Pending Products section provides additional preliminary information on the following pending products: ADM2861E, ADM2863E, and ADM2865E (see Table 21 on the datasheet).
Table 17 on the datasheet shows the summary description of each generic.
