The ISO1211D from Texas Instruments is a single-channel isolated digital input receiver, suitable for 24V isolated digital input modules. It supports a wide input voltage range of 9V to 300V DC and AC, with reverse polarity protection up to ±60V. The device offers a maximum data rate of 4Mbps and a working isolation voltage of 400Vrms.
Key electrical specifications include a supply voltage range of 2.25V to 5.5V and a high transient immunity (CMTI) of ±70kV/µs. It features accurate current limiting for low-power dissipation, with values from 2.2mA to 2.47mA for Type 3 inputs, adjustable up to 6.5mA. The ISO1211D also includes wire-break detection and can be configured as a sourcing or sinking input.
This component is housed in a compact 8-SOIC package and is designed for surface mounting. It operates within an ambient temperature range of -40°C to +125°C. The ISO1211D is compliant with IEC 61131-2 standards for 24V isolated digital inputs and holds safety certifications including VDE, UL, IEC 60950-1, IEC 62368-1, IEC 61010-1, and GB 4943.1-2011.
It is functional safety capable, with documentation available to aid in functional safety system design. The device is suitable for applications requiring robust isolation and accurate digital input signal reception in industrial environments.
