1 Mbps的4通道数字隔离器 1-Mbps QUAD DIGITAL ISOLATORS
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 ’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.
A periodic update pulse is sent across the barrier to ensure the proper dc level of the output. If this dc-refresh pulse is not received, the input is assumed to be unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state. See ISO7240CF SLLS869 or contact TI for a logic low failsafe option.
The ISO7241A may be powered from either 3.3-V or 5-V supplies on either side in any 3.3-V / 3.3-V, 5-V / 5-V, 5-V / 3.3-V, or 3.3-V / 5-V combination. Note that the signal input pins are 5-V tolerant regardless of the voltage supply level being used.
This device is characterized for operation over the ambient temperature range of –55°C to 125°C.
