The Renesas ±15kV IEC61000 ESD protected, micro-power, wide supply range transceivers for differential communication. It operate with VCC ≥ 2.7V and have maximum supply currents as low as 100μA with both the transmitter (Tx) and receiver (Rx) enabled. These transceivers have very low bus currents, so they present less than a 1/8 unit load to the bus. This allows more than 256 transmitters on the network without violating the RS-485 specification’s 32 unit load maximum.

Single 1.8V, 3V, or 3.3V supply
Ultra low shutdown supply current of 10nA
Up to 65mV hysteresis for improved noise immunity
Data rates from 128kbps to 460kbps
Specified for +125°C operation
1/8 unit load allows up to 256 devices on the bus
Half and full duplex pinouts
