SMBus Accelerator 5-Pin SOT-23 T/R

The ISL88694 SMBus accelerator (SMA) is a dual active pull-up bus terminator designed to improve data transmission speed on SMBus or similar 2-wire serial bus interfaces. The ISL88694 is also compatible to the I2C serial bus. The level for VTRIPH is controlled by a bandgap voltage referred to VDD. This feature makes the switching behavior invariant for all power supply voltages between 2.7V and 5.5V. The SMA permits operation of the bus at frequencies up to 100kHz, despite the capacitive loads of multiple devices and/or long PC board traces. Enhanced ESD protection on the accelerator pins are guaranteed to withstand 8kV ESD (HBM) events.
