ISL88694 SMBus Accelerator (SMA) 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 with the I2C serial bus.

The SMA detects rising input transitions with two internal voltage references and two comparators per channel.

After the voltage on a data line crosses the first threshold (VTRIPL), the boost pull-up current source is activated to speed tr
