Introduction

The ISO676x-Q1 devices are high-performance six-channel digital isolators that offer a 5000 VRMS isolation rating in accordance with UL 1577, making them well-suited for cost-sensitive applications with such requirements. These devices are also certified by VDE, TUV, CSA, and CQC. While isolating CMOS or LVCMOS digital I/Os, the ISO676x-Q1 devices provide high electromagnetic immunity, low radiation, and low power consumption. The logic input and output buffers of each isolated channel are isolated by TI's dual-capacitor silicon dioxide (SiO₂) insulating gate. The ISO676x series devices are available in all possible pin configurations, so all six channels can be in the same direction, or one, two, or three channels can be in the reverse direction while the remaining channels are in the forward direction. If there is a loss of input power or signal, devices without the suffix F default to a high output, while devices with the suffix F default to a low output. When used in conjunction with isolated power supplies, these devices help prevent noise currents on data buses such as CAN and LIN from damaging sensitive circuits. Thanks to innovative chip design and wiring technology, the electromagnetic compatibility of the ISO676x-Q1 devices has been significantly enhanced, which can mitigate system-level ESD, EFT, and surge issues and meet radiation standards. The ISO676x-Q1 series devices are available in a 16-pin SOIC wide-body (DW) package and are a pin-to-pin upgrade from previous generations of devices.
