RAA788178 - RS-485 Transceivers

Download the RAA788178 datasheet PDF. This datasheet also covers the RAA788170 variant, as both devices belong to the same rs-485 transceivers family and are provided as variant models within a single manufacturer datasheet.

General Description

3.

.

Key Features

  • IEC61000 ESD protection on RS-485 I/O pins: ±15kV.
  • Class 3 ESD level on all other pins: >7kV HBM.
  • ±3kV EFT immunity of bus I/O pins.
  • Full fail-safe (open, short, terminated/floating) receivers.
  • Hot plug - Tx and Rx outputs remain three-state during power-up.
  • True 1/8 unit load allows up to 256 devices on the bus.
  • Single 3.3V supply.
  • High data rates: up to 20Mbps.
  • Low quiescent supply current: 800µA (Max).
  • Ultra low shutdown supply curren.

Datasheet RAA788170, RAA788172, RAA788173, RAA788175, RAA788176, RAA788178 3.3V, Full Fail-Safe, Low-Power, RS-485 Transceivers with 3kV EFT Immunity and 15kV ESD Protection The RAA78817x family (RAA788170, RAA788172, RAA788173, RAA788175, RAA788176, RAA788178) of 3.3V powered single transceivers feature high output drive and high EFT and ESD protection. The devices are immune to ±3kV IEC61000-4-4 EFT transients and withstand ±15kV IEC61000-4-2 ESD strikes without latch-up. These devices have low bus currents (+125µA/-100µA), so they present a true 1/8 unit load to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification 32 unit load maximum, and without using repeaters.
