8.3 Device Functional Modes

Table 8-1 through Table 8-3 show the device functional modes.

Table 8-1 Each Driver
INPUTS(1) OUTPUT DRIVER STATUS
DIN FORCEON FORCEOFF VALID RIN
RS-232 LEVEL		 DOUT
X X L X Z Powered off
L H H X H Normal operation with
auto-powerdown disabled
H H H X L
L L H Yes H Normal operation with
auto-powerdown enabled
H L H Yes L
X L H No Z Powered off by auto-powerdown feature
(1) H = high level, L = low level, X = irrelevant, Z = high impedance
