Product Details

General Description

The CA-IF4805/20/50 family of devices are low-power transceivers for RS-485 and RS-422 communications in harsh environments. All devices have ±30V fault protection for overvoltage conditions on the communication bus lines that ensure robust protection on the bus. They also feature ±15V of common-mode range (CMR), making them ideal for electrically noisy environments where different systems have shifting ground levels relative to each other and long-distance transmission. The bus pins of these devices are protected against ±15kV (for the full-duplex parts) and ±30kV (for the half-duplex parts) electro-static discharge (ESD) shocks, eliminating the need for additional system-level protection components.

The CA-IS48XX family devices are specified over the -40°C to +125°C operating temperature range and are available in small 8-pin MSOP, 8-pin DFN packages for space-constrained applications, and 8-pin SOIC for drop-in compatibility.
