PRODUCTION DATA.
Either supply rail may be powered on or off in any order without producing a glitch on the I/Os (that is, where the output erroneously transitions to VCC when it should be held low). Glitches of this nature can be misinterpreted by a peripheral as a valid data bit, which could trigger a false device reset of the peripheral, a false device configuration of the peripheral, or even a false data initialization by the peripheral. For more information regarding the power up glitch performance of the AXC family of level translators, see the Glitch Free Power Sequencing With AXC Level Translators application report
