Product data sheet
All channels have the same electrical characteristics and there is minimal deviation from
one output to another in voltage or propagation delay. This is a benefit over discrete
transistor voltage translation solutions, since the fabrication of the switch is symmetrical.
The translator provides excellent ESD protection to lower voltage devices, and at the
same time protects less ESD-resistant devices.

2-bit bidirectional translator for SDA and SCL lines in mixed-mode I
Standard-mode, Fast-mode, and Fast-mode Plus I
Less than 1.5 ns maximum propagation delay to accommodate Standard mode and
Fast mode I
Allows voltage level translation between:
Provides bidirectional voltage translation with no direction pin
Low 3.5
distortion
Open-drain I
5 V tolerant I
High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW
Lock-up free operation for isolation when EN = LOW
Flow through pinout for ease of printed-circuit board trace routing
ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
JESD22-A115, and 1000 V CDM per JESD22-C101
Packages offered: SO8, TSSOP8, VSSOP8, XQFN8
