SLLSEX0 – NOVEMBER 2016 2 ISO154x-Q1 Low-Power Bidirectional I C Isolators
1 Features 3 Description The ISO1540-Q1 and ISO1541-Q1 devices are lowpower, bidirectional isolators that are compatible with
I2C interfaces. These devices have logic input and
output buffers that are separated by Texas
Instruments Capacitive Isolation technology using a
silicon dioxide (SiO2) barrier. When used with isolated
power supplies, these devices block high voltages,
isolate grounds, and prevent noise currents from
entering the local ground and interfering with or
damaging sensitive circuitry. 1 Qualified for Automotive Applications
AEC-Q100 Qualified With the Following Results:
– Device Temperature Grade 1: –40°C to
+125В°C Ambient Operating Temperature
– Device HBM ESD Classification Level 3A
– Device CDM ESD Classification Level C6
Isolated Bidirectional, I2C Compatible,
Communication …
