10-bit level-shifting bus switch with output enable
9.3 ON resistance
[1] Typical values are measured at T

=25C and nominal V
CC
.
[2] Measured by the voltage drop between the An and Bn terminals at the indicated current through the switch. ON-state resistance is
determined by the lower of the voltages of the two (An or Bn) terminals.
