The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are oriented in the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic input and output buffer separated by TI's silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4000 V PK per VDE. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2017-08-06 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2018-05-04 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2019-03-21 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2019-04-02 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2019-06-21 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2021-04-25 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2022-09-26 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2022-10-21 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2023-01-07 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2024-06-22 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2025-02-02 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2025-12-12 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2026-01-18 https://elecena.pl/product/9716157/iso7221adr-interface-isolator-2-channel-so-8 2026-02-13
