ISO7142CCDBQ

ISO7142CC Low-Power Quad Channel Digital IsolatorTexas Instruments ISO7142CC Low-Power Quad Channel Digital Isolator provides galvanic isolation up to 2500V RMS for 1 minute per UL and 4242V PK per VDE. The ISO7142CC is a quad-channel isolator with two forward and two reverse-direction channels. This device is capable of the maximum data rate of 50Mbps with 5V supplies and 40Mbps with 3.3V or 2.7V supplies. ISO7142CC has integrated filters on the inputs to support noise-prone applications. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO 2 ) insulation barrier. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. This device has TTL input thresholds and can operate from 2.7V, 3.3V, and 5V supplies.
