FEATURES
• Bidirectional buffer for SDA and SCL lines increases fan out
and prevents SDA and SCL corruption during live board
insertion and removal from multipoint backplane systems
• Compatible with I2C-bus Standard-mode, I2C-bus Fast-
mode, and SMBus standards
• Built-in ∆V/∆t rise time accelerators on all SDA and SCL
lines (0.6 V threshold) requires the bus pull-up voltage and
supply voltage (VCC) to be the same
• Active HIGH ENABLE input
• Active HIGH READY open-drain output
• High-impedance SDA and SCL pins for VCC =0V
• 1 V precharge on all SDA and SCL lines
• Supporting clock stretching and multiple master arbitration/
synchronization
• Operating power supply voltage range: 2.7 V to 5.5 V
• 0 Hz to 400 kHz clock frequency
• ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per
JESD22-A115, and 1000 V CDM per JESD22-C101
• Latch-up testing is done to JEDEC Standard JESD78 which
exceeds 100 mA
• Packages offered: SO8, TSSOP8 (MSOP8)
