The DS8113 supports three smart card V
1.8V, 3V, and 5V. The power select is controlled by the
1_8V and 5V/3V signals as shown in Table 3. The 1_8V
signal has priority over 5V/3V. When 1_8V is asserted
high, 1.8V is applied to VCC when the smart card is
active. When 1_8V is deasserted, 5V/3V dictates V
power range. V

time, the DS8113 enters stop mode. To avoid acciden-
tal entry into stop mode, the state of 1_8V and 5V/3V
must not be changed simultaneously. A minimum delay
of 100ns should be observed between changing the
states of 1_8V and 5V/3V. See Figure 9 for the recom-
