The SCLT3 series is an octal industrial digital input IC which drastically reduces the power dissipation of the digital input modules. Its current-sinking inputs can be configured for Type 1, Type 2, or Type 3 inputs as per IEC 61131-2 with few external components. The SCLT3 series includes a serial interface which translates, conditions and serializes the data to CMOS-compatible signals through SPI. Combining its daisy-chaining capability with its accurate current limitation, the SCLT3 series enhances the I/O module’s density by cutting the power dissipation and reducing the number of optocouplers. The SCLT3 series can be evaluated thanks to the STEVAL-IFP030V1 evaluation board. For detailed application guidelines refer to AN2846. https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2021-04-03 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2021-04-16 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2021-07-17 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2021-12-04 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2022-04-07 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2022-06-13 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2022-06-25 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2023-09-02 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2024-06-06 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2024-06-24 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2024-11-20 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2025-07-04 https://elecena.pl/product/17494467/sclt3-8bt8-tr-protected-digital-input-termination-with-serialized-state-transfer 2025-07-13
