Texas Instruments ISO7240CF
The ISO7240CF device has an input disable function on pin 7, and a selectable high or low failsafe-output function with the CTRL pin (pin 10). The failsafe output is a logic high when a logic high is placed on the CTRL pin or the pin is left unconnected. The input disable function of the ISO7240CF device prevents data from being passed across the isolation barrier to the output.- Min Voltage : 3.3V
- Max Voltage : 5V
- Channels : 4
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C

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.
