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#, CSA# (CS# in 68 Mode), CSB# and all modem inputs. Also, RXA and RXB inputs must idle
HIGH while asleep. Floating inputs will result in sleep currents in the mA range.
