The ISO733x family of devices provides galvanic isolation up to 3000 VRMS for 1 minute per UL 1577 and 4242 VPK per VDE V 0884-10. These devices have three isolated channels comprised of logic input and output buffers separated by a silicon dioxide (SiO2) insulation barrier.
The ISO7330 has all three channels in the same direction while ISO7331 has two channels in forward and one channel in reverse direction. See the section for further details.
Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO733x family of devices has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. The ISO733x family of devices has TTL input thresholds and operates from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO733x family of devices has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.

DIGI-ISO-EVM — 通用數位隔離器評估模組
DIGI-ISO-EVM 是一款評估模組 (EVM)，可評估任何 TI 單通道、雙通道、三通道、四通道或六通道數位隔離器裝置，並提供五種不同封裝 - 8 接腳窄體 SOIC (D)、8 接腳寬體 SOIC (DWV)、16 接腳寬體 SOIC (DWW)、16 接腳超寬體 SOIC (DWW) 和 16 接腳 (DBQ) 封裝。EVM 具備足夠 Berg 接腳選項，可用於評估具最少外部零組件的裝置。
ISO7310C-EVM — 單通道數位隔離器評估模組
ISO7310C-EVM 評估模組 (EVM) 可協助您評估裝置性能，支援快速開發與分析隔離式系統。此 EVM 支援評估採用 8 針腳 SOIC 封裝的任何單通道或雙通道數位隔離器。
ISO7310C 數位隔離器可提供符合 UL 標準且高達 3000 VRMS 的電氣隔離能力（持續 1 分鐘），以及符合 VDE 標準的 4242 VPK 電氣隔離能力。此裝置具有一個隔離通道，且該通道有邏輯輸入與輸出緩衝器，兩者之間以二氧化矽 (SiO2) 絕緣隔離層加以隔離。與隔離電源結合使用時，此這些裝置可防止資料匯流排或其他電路上的雜訊進入本地接地並干擾或損壞敏感電路。
