Power-Up/Power-Down Sequencing
FXL translators offer an advantage in that either VCC
may be powered up first. This benefit derives from the
chip design. When either VCC is at 0 volts, outputs are in
a HIGH-Impedance state. The control inputs (T/Rn and
OE) are designed to track the VCCA supply. A pull-up
resistor tying OE to VCCA should be used to ensure that
bus contention, excessive currents, or oscillations do not
occur during power-up/power-down. The size of the pull-
up resistor is based upon the current-sinking capability
of the OE driver.
The recommended power-up sequence is the following:
1. Apply power to either VCC.
2. Apply power to the T/Rn inputs (Logic HIGH for A-to-B
operation; Logic LOW for B-to-A operation) and to the
respective data inputs (A Port or B Port). This may
occur at the same time as Step 1.
3. Apply power to other VCC.
4. Drive the OE input LOW to enable the device.
The recommended power-down sequence is the follow-
ing:
1. Drive OE input HIGH to disable the device.
2. Remove power from either VCC.
3. Remove power from other VCC.
