DESCRIPTION
The ISO7240, ISO7241 and ISO7242 are quad-channel digital isolators with multiple channel configurations and
output enable functions. These devices have logic input and output buffers separated by TI’s silicon dioxide
(SiO
) isolation barrier. Used in conjunction with isolated power supplies, these devices block high voltage,
2
isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging
sensitive circuitry.
The ISO7240 has all four channels in the same direction while the ISO7241 has three channels the same
direction and one channel in opposition. The ISO7242 has two channels in each direction.
The C option devices have TTL input thresholds and a noise-filter at the input that prevents transient pulses from
being passed to the output of the device. The M option devices have CMOS V
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
output. When the inputs are disabled, the outputs are set by the CTRL pin.
These devices 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.
These devices are characterized for operation over the ambient temperature range of –40°C to 125°C.
