SLLSEA5B –MARCH 2012–REVISED JUNE 2012  
Low-Power Dual Digital Isolators  
Check for Samples: ISO7421E-Q1  
1
FEATURES  
DESCRIPTION  
The ISO7421E-Q1 provides double galvanic isolation  
of up to 2.5 KVrms for 1 minute per UL. This digital  
isolator has two isolation channels in a bi-directional  
configuration. Each isolation channel has a logic input  
and output buffer separated by a silicon oxide (SiO2)  
insulation barrier. Used in conjunction with isolated  
power supplies, these devices prevent noise currents  
on a data bus or other circuits from entering the local  
ground and interfering with or damaging sensitive  
circuitry.  
•
•
Qualified for Automotive Applications  
AEC-Q100 Qualified with the following results:  
–
Device Temperature Grade 1: -40°C to  
+125°C Ambient Operating Temperature  
Range  
–
–
Device HBM ESD Classification Level H3A  
Device CDM ESD Classification Level C4  
•

•
•
Propagation Delay Less Than 20 ns  
Low Power Consumption  
The devices have TTL input thresholds and require  
two supply voltages, 3.3  
V or 5 V, or any  
Wide Ambient Temperature: –40°C to 125°C  
Safety and Regulatory Approvals  
combination. All inputs are 5-V tolerant when supplied  
from a 3.3-V supply.  
–
4 kV peak Maximum Isolation, 2.5 kVrms  
per UL 1577, IEC/VDE and CSA Approved,  
IEC 60950-1, IEC 61010-1 End Equipment  
Standards Approved. All Approvals  
Pending.  
Note: The ISO7421E-Q1 is specified for signaling  
rates up to 50 Mbps. Due to their fast response time,  
under most cases, these devices will also transmit  
data with much shorter pulse widths. Designers  
should add external filtering to remove spurious  
signals with input pulse duration < 20 ns if desired.
