3.3V Voltage Supply, Up to 12Mbps Transmission Speeds, Half-Duplex RS-485 Transceiver - SCM3402ASI

Mornsun launched a new half-duplex transceiver SCM3402ASI(+3.3V voltage supply), as an extention of SCM3401BFA(+5V voltage supply). Designed for the RS-485 network, the new transceiver SCM3402ASI is fully compliant with TIA/EIA-485A standards. 
The SCM3402ASI transceiver contains a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, the driver and the receiver output a high-impedance state.
With a 1/8 load, the SCM3402ASI transceiver allows up to 256 transceivers on a Bus to achieve up to 12Mbps error-free data transmission. Its operating voltage range is 3.0-3.6V, and protections include fail-safe, over-temperature, limiting current and over current.

Applications of RS-485 Transceiver  - SCM3402ASI

Widely used in applications of industrial automation, building automation, smart electricity meters, remote signal interaction, transmission, etc.
