4通道数字隔离器 QUAD DIGITAL ISOLATORS
DESCRIPON
See the Product Notification section. The ISO7240A, ISO7241A and ISO7242A are quad-channel digital isolators with multiple channel configurations and output enable functions. These devices have logic input and output buffers separated by TI’s silicon dioxide SiO2 isolation barrier. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.
