SWITCHING CHARACTERISTICS (continued)
(VCC = +3.0V to +3.6V, TA = -40NC to +125NC, unless otherwise noted. Typical values are at VCC = +3.3V and TA = +25NC.) (Notes 2, 3)
Note 2: All devices are 100% production tested at TA = +25NC. Specifications for all temperature limits are guaranteed by design.
Note 3: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 4: DVOD and DVOC are the changes in VOD and VOC, respectively, when the DI input changes state.
Note 5: Capacitive load includes test probe and fixture capacitance.
Note 6: The timing parameter refers to the driver or receiver enable delay when the device has exited the initial hot-swap protect
state and is in normal operating mode.
Note 7: Shutdown is enabled by driving RE high and DE low. The device is guaranteed to have entered shutdown after tSHDN has
elapsed.
Note 8: Parameter is guaranteed by characterization and not production tested.
