The ADM3491EARZ is a 3.3 V, low-power, full-duplex transceiver designed for RS-485 and RS-422 communication. It supports data rates up to 12 Mbps and includes ±15 kV ESD protection on the RS-485 input/output pins, making it suitable for industrial environments. The device operates over a supply voltage range of 3 V to 3.6 V and features a receiver hysteresis of 50 mV for noise immunity.
This transceiver can drive up to 32 nodes on a bus and has a common-mode input range of -7 V to +12 V. It includes thermal shutdown and short-circuit protection for robust operation. The full-duplex design allows simultaneous data transmission and reception on dedicated differential lines.
The ADM3491EARZ is offered in a 14-lead narrow SOIC package (14-SOIC) with a surface-mount mounting type. It is specified for an industrial temperature range of -40°C to +85°C, making it suitable for a wide range of applications including power/energy metering, telecommunications, and industrial control.
The supply voltage range is 3 V to 3.6 V.
The datasheet specifies a data rate of 12 Mbps for the ADM3491E.
The operating temperature range is -40°C to +85°C.
The ADM3491EARZ is offered in a 14-SOIC (0.154", 3.90mm Width) surface-mount package.
It supports RS-422 and RS-485 protocols.
The RS-485 input/output pins have ±15 kV ESD protection.
Up to 32 transceivers can be on the bus.
