DC ELECTRICAL CHARACTERISTICS
TA = -40
Test 1: The following inputs must remain steady at VCC or GND state to minimize sleep current: A0-A2, D0-D7,
IOR#, IOW# (R/W#), CSA# (CS#), CSB# (A3) and all modem inputs. Also, RXA and RXB inputs must idle
HIGH while asleep. Floating inputs may result in sleep currents in the mA range.
