说明

See the Product Notification section. The ISO7241A is a quad-channel digital isolator with multiple channel configurations and output enable functions. This device has logic input and output buffers separated by TI’s silicon dioxide (SiO₂) isolation barrier. Used in conjunction with isolated power supplies, this device blocks high voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.

The ISO7241A has three channels the same direction and one channel in opposition.

This device has TTL input thresholds and a noise-filter at the input that prevents transient pulses from being passed to the output of the device.
