ISO7240CFDWRG4

具有可选择故障保护输出4通道数字隔离器 QUAD DIGITAL ISOLATOR WITH SELECTABLE FAILSAFE OUTPUT

Description

The ISO7240x, ISO7241x, and ISO7242x devices are quad-channel digital isolators with multiple channel

configurations and output-enable functions. These devices have logic-input and logic-output buffers

separated by Texas Instrument’s silicon-dioxide SiO2 isolation barrier. Used in conjunction with isolated power supplies, these devices help block high voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.
