8.4 Device Functional Modes

Table 8-1 shows the functional modes for the device.

Table 8-1 Function Table
VCCI1VCCOINPUT
(INx)3		OUTPUT
(OUTx)		COMMENTS
PUPUHHNormal Operation:
A channel output assumes the logic state of its input.
LL
XDefaultThe channel output assumes the selected default option.
PDPUXDefaultWhen VCCI is unpowered, a channel output assumes the logic state based on the selected default option. Default is High for the device without the F suffix and Low for device with the F suffix.
When VCCI transitions from unpowered to powered-up, a channel output assumes the logic state of the input.
When VCCI transitions from powered-up to unpowered, channel output assumes the selected default state.
XPDXUndeterminedWhen VCCO is unpowered, a channel output is undetermined and tri state2.
When VCCO transitions from unpowered to powered-up, a channel output assumes the selected default option.
  1. VCCI = Input-side VCC; VCCO = Output-side VCC; PU = Powered up (VCC ≥ 1.54 V); PD = Powered down (VCC ≤ 1.54); X = Irrelevant; H = High level; L = Low level ; Z = High Impedance.
  2. The outputs are in undetermined state when 1.54 V < VCCI, VCCO < 1.54 V.
  3. A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output.
