7.4 Device Functional Modes

Table 7-2 lists the ISO7810x functional modes.

Table 7-2 Function Table
VCC1VCC2(1)INPUT
(IN)(3)		OUTPUT
(OUT)		COMMENTS
PUPUHHNormal Operation:
A channel output assumes the logic state of the input.
LL
OpenDefaultDefault mode: When IN is open, the corresponding channel output goes to the default logic state. Default = High for ISO7810 and Low for ISO7810F.
PDPUXDefaultDefault mode: When VCC1 is unpowered, a channel output assumes the logic state based on the selected default option. Default = High for ISO7810 and Low for ISO7810F.
When VCC1 transitions from unpowered to powered-up, a channel output assumes the logic state of the input.
When VCC1 transitions from powered-up to unpowered, channel output assumes the selected default state.
XPDXUndeterminedWhen VCC2 is unpowered, a channel output is undetermined (2).
When VCC2 transitions from unpowered to powered-up, a channel output assumes the logic state of the input
(1) PU = Powered up (VCC ≥ 2.25 V); PD = Powered down (VCC ≤ 1.7 V); X = Irrelevant; H = High level; L = Low level
(2) The outputs are in undetermined state when 1.7 V < VCC1, VCC2 < 2.25 V.
(3) A strongly driven input signal can weakly power the floating VCC via an internal protection diode and cause undetermined output.
