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#, 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. For PowerSave feature that isolates address, data
and control signals, see the XR16V2551 data sheet.
