General Description The CS485xx family of devices are low-power half-duplex transceivers for RS-485/RS-422 munications in harsh environments. All devices feature ±20k V electro-static discharge (ESD) protection for the bus pins (A and B), eliminating the need for additional system level protection ponents. The CS485xx family of devices contain one driver(TX) and one receiver(RX), operates over the +3V to +5.5V supply range, making these devices convenient for designers to use one part with either +3.3V or +5V supply systems. The CS48520x devices can transmit and receive at data rates up to 20Mbps, while the CS48505x devices are specified for data rates up to 500kbps. These devices also include failsafe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are shorted or open. All devices are specified over the -40°C to +125°C wide operating temperature range and are available in small 8pin MSOP, 8-pin DFN...
