General Description for the communication interface. They also feature ±15V wide common-mode range (CMR), this feature was specifically designed for systems where there is a large common-mode voltage present due to either nearby electrically noisy equipment or large ground differences due to different earth grounds or long distance transmission. The bus pins of these devices are protected against ±15kV (for the full-duplex transceivers) and ±30kV (for the half-duplex transceivers) electro-static discharge (ESD) shocks, eliminating the need for additional system level protection components. The CA-IF48xx family of devices contains 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 CA-IF48xxHS/HM/HD devices provide halfduplex transceivers, and the CA-IF48xxFS/FM/FD devices provide full-duplex transceivers. The CA-IF4820 and CAIF4850 can transmit and receive at data rates up to 20Mbps and up to 50Mbps respectively, while the CAIF4805 is specified for data rates up to 500kbps. These devices also include fail-safe circuitry, guaranteeing a logichigh 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 packages for space constrained applications and 8-pin SOIC for drop-in compatibility. Device Information Package Package size (NOM) CA-IF48xxxS SOIC8 3.9mm*4.9mm CA-IF48xxxM MSOP8 3mm*3mm CA-IF48xxxD DFN8 3mm*3mm Part number The CA-IF48xx family of devices are low-power transceivers for RS-485/RS-422 communications in harsh environments. All devices have ±30V fault protection for overvoltage conditions on the bus lines that ensure robust protection Copyright © 2020, Chipanalog Incorporated Shanghai Chipanalog Microelectronics Co., Ltd. 1 PDF
