5 Description (Continued)

The C option devices have TTL input thresholds and a noise-filter at the input that prevents transient pulses from

have the input noise-filter or the additional propagation delay.

The ISO7240CF 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 it is left

unconnected. If a logic-low signal is applied to the CTRL pin, the failsafe-output becomes a logic-low output

state. The ISO7240CF input disable function prevents data from being passed across the isolation barrier to the

These devices may be powered from 3.3-V or 5-V supplies on either side in any combination. Note that the

signal input pins are 5-V tolerant regardless of the voltage supply level being used.

These devices are characterized for operation over the ambient temperature range of –40°C to 125°C.
