APPLICATION INFORMATION
Hot-Plugging
These devices are designed to operate in “hot swap” or “hot pluggable” applications. Key features for hot-
pluggable applications are power-up, power-down glitch free operation, default disabled input/output pins, and
receiver failsafe. An internal Power-On Reset circuit keeps the outputs in a high-impedance state until the supply
voltage has reached a level at which the device will reliably operate. This ensures that no spurious transitions
(glitches) will occur on the bus pin outputs as the power supply turns on or turns off.
As shown in the device FUNCTION TABLES, the ENABLE inputs have the feature of default disable on both the
driver enable and receiver enable. This ensures that the device will neither drive the bus nor report data on the R
pin until the associated controller actively drives the enable pins.
