ISO7241CDW Quad-channel 25-Mbps digital isolator

Description for the
ISO7241C
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. Used
in conjunction with isolated power supplies, these devices help block high voltage,
isolate grounds, and prevent noise currents from entering the local ground and
interfering with or damaging sensitive circuitry.
The ISO7240x family of devices
has all four channels in the same direction. The ISO7241xfamily of devices has
three channels in the same direction and one channel in the opposition direction.
The ISO7242x family of devices has two channels in each direction.
The devices with the C
suffix (C option) 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 devices with the M suffix (M option) have CMOS VCC/2 input thresholds and
do not have the input noise filter or the additional propagation delay.
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 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 input disable function of the ISO7240CF device prevents data
from being passed across the isolation barrier to the output. When the inputs
are disabled or VCC1 is powered down, the outputs are set by the CTRL pin.
These devices can be
powered from 3.3-V or 5-V supplies on either side, in any combination. The
signal input pins are 5-V tolerant regardless of the voltage supply level that
is used.
These devices are
characterized for operation over the ambient temperature range of –40°Cto
+125°C.
