Description
The CA-IS374x devices are high-performance quad-channel
digital isolators with precise timing characteristics and low
power consumption. The CA-IS374x devices provide high
electromagnetic immunity and low emissions, while
isolating CMOS digital I/Os. All device versions have Schmitt
trigger input for high noise immunity. Each isolation channel
consists of a transmitter and a receiver separated by silicon
dioxide (SiO2) insulation barrier. The CA-IS3740 device has
all four channels in the same direction with output enable

on the output side (B side), the CA-IS3741 device has three
forward and one reverse-direction channels with output
enable on both sides, the CA-IS3742 device has two forward
and two reverse-direction channels with output enable on
both sides, and the CA-IS3745 device has the same channel
configuration as CA-IS3740 without output enable. All
devices have fail-safe mode option. If the input power or
signal is lost, default output is low for devices with suffix L
and high for devices with suffix H.
CA-IS374x devices has high insulation capability to handle
noise and surge on a data bus or other circuits from entering
the local ground and interfering with or damaging sensitive
circuitry. High CMTI ability promises the correct
transmission of digital signal. The CA-IS374x devices are
available in 16-pin narrow body SOIC and 16-pin wide body
SOIC packages. All products have > 2.5kVrms isolation rating,
and products in wide-body packages support insulation
withstanding up to 5kVrms.

9 Detailed Description
Preview Version
9.1 Theory of Operation
The CA-IS374x family of devices use a simple ON-OFF keying (OOK) modulation scheme to transmit signal across the SiO2
isolation capacitors that provide a robust insulation between two different voltage domain and act as a high frequency signal
path between the input and the output. The transmitter (TX) modulates the input signal onto the carrier frequency, that is, TX
delivers high frequency signal across the isolation barrier in one input state and delivers no signal across the barrier in the other
input state. Then the receiver rebuilds the input signal according to the detected in-band energy. If the ENx pin is low then the
output goes to high impedance state and will be pulled up to VDDO (CA-IS374xH) or pull down to the corresponding GND (CAIS374xL). This simple architecture offers a robust isolated data path and requires no special considerations or initialization at
start-up. The capacitor-based signal path is fully differential to maximize noise immunity, which is also known as common-mode
transient immunity. Advanced circuitry techniques are applied for better EMI introduced by the carrier signal and IO switching.
The capacitively-coupled architecture provides much higher electromagnetic immunity compared to the inductively-coupled
one. And OOK modulation scheme eliminates the missing-pulse error that occurs in the pulse modulation method. A simplified
functional block diagram and conceptual operation waveforms of a single channel is shown in Figure 9-1 and Figure 9-2.

OPERATION
Normal operation mode:
A channel’s output follows the input state
Default output fail-safe mode:
If a channel’s input is left open, its output goes to the
default value (Low for CA-IS374xL and High for CA-IS374xH).
High impedance mode:
If Enable pin is tied to low, the output will be in high-Z mode
Default output fail-safe mode:
If the input side VDD is unpowered, the outputs go in to the
default output fail-safe mode (Low for CA-IS374xL and High
for CA-IS374xH)
If the output side VDD is unpowered, the outputs’ states are
undetermined.5
NOTE:
1. VDDI = Input-side VDD; VDDO = Output-side VDD; PU = Powered up (VCC ≥ 2.375 V); PD = Powered down (VCC ≤ 2.25 V); X = Irrelevant; H = High
level; L = Low level; Z = High Impedance.
2. A strongly driven input signal can weakly power the floating VDD through an internal protection diode and cause undetermined output.
3. It is recommended that the enable inputs be connected to an external logic high or low level when the CA-IS374x is operating in noisy
environments.
4. No Connect (NC) replaces ENA on CA-IS3740/45. No Connect replaces EN2 on the CA-IS3745. No Connects are not internally connected and
can be left floating, tied to VDD, or tied to GND.
5. The outputs are in undetermined state when 2.25V < VDDI, VDDO < 2.375 V.
Table 9-2 provides the Enable input truth table for the CA-IS374x devices.

NOTE:
1. Enable inputs ENA and ENB can be used for multiplexing, for clock sync, or other output control. ENA, ENB logic operation is summarized for
each isolator product in Table 9-2. These inputs are internally pulled-up to local VDD allowing them to be connected to an external logic level
(high or low) or left floating. To minimize noise coupling, do not connect circuit traces to ENA or ENB if they are left floating. If ENA, ENB are
unused, it is recommended they be connected to an external logic level, especially if the CA-IS374x is operating in a noisy environment.
2. X = Irrelevant; H = High level; L = Low level.

10 Application and Implementation
Unlike optocouplers, which need external components to improve performance, provide bias, or limit current, the CA-IS374x
family device CMOS digital isolator needs only two external VDD bypass capacitors (0.1μF to 1 μF) to operate. Its TTL level
compatible input terminals draw only micro amps of leakage current, allowing them to be driven without external buffering
circuits. The output terminals have a characteristic impedance of 50 Ω (rail-to-rail swing) and are available in both forward and
reverse channel configurations. Figure 10-1 shows the typical application of CA-IS3742 device. And the circuit of Figure 10-2 is
typical for most applications of CA-IS37xx series products and is as easy to use as a standard logic gate.
