Chuantu microelectronics high speed and high performance rs-485/422 transceiver series

CA-IF48XX It's industrial grade RS-485/422 whole / Half duplex transceiver interface chip series . It can be used in harsh and harsh industrial environments . The bus pins of these devices can withstand high levels IEC Electrical fast transients (EFT) and IEC Electrostatic discharge (ESD), This eliminates the need to use other system level protection components .

The common mode voltage range of this series of devices reaches ±15V、 The fault protection range reaches ±30V. Therefore, these devices are suitable for long cables and harsh environments .CA-IF48XX Series devices can provide miniaturization SOP8、MSOP8、DFN8 encapsulation , Suitable for space limited applications . The operating temperature range of these devices in natural ventilation environment is –40°C to 125°C.

One of the chips in this series CA-IF4888 It's a low power RS-485 Non polar transceiver , This transceiver has an automatic bus polarity correction function . Hot swap , This device starts when the bus is idle 76ms Inside （ Typical values ） Check and correct bus polarity .
