GENERAL DESCRIPTION The ADuM140x are 4-channel digital isolators based on Analog
Devices’ iCoupler® technology. Combining high speed CMOS
and monolithic air core transformer technology, these isolation
components provide outstanding performance characteristics
superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with
optocouplers. The typical optocoupler concerns regarding
uncertain current transfer ratios, nonlinear transfer functions,
and temperature and lifetime effects are eliminated with the
simple iCoupler digital interfaces and stable performance
characteristics. The need for external drivers and other discretes
is eliminated with these iCoupler products. Furthermore,
iCoupler devices consumes one-tenth to one-sixth the power of
optocouplers at comparable signal data rates.
The ADuM140x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models operate with the supply
voltage on either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. In
addition, the ADuM140x provides low pulse-width distortion
(<2 ns for CRW grade) and tight channel-to-channel matching
(<2 ns for CRW grade). Unlike other optocoupler alternatives,
the ADuM140x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and during power-up/power-down conditions.

SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION14.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V; all min/max specifications apply over the entire recommended operation range, unless other-
wise noted; all typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V.
Table 1. See Notes on next page.
1 All voltages are relative to their respective ground. The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load
present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section on
Page 20. See through for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See

Figure 14DD1 and IDD2 supply currents as a function of data rate for ADuM1400/ADuM1401/ADuM1402 channel configurations. The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.
4 The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed. tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
7 Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier. CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See through for information
on per-channel supply current for unloaded and loaded conditions. See the section on Page 20 for guidance on calculating the per-channel sup-
ply current for a given data rate.
