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 input (OE) is
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 device driving the OE pin.
The recommended power-up sequence is the following:
1. Apply power to the first VCC.
2. Apply power to the second VCC.
3. Drive the OE input LOW to enable the device.
The recommended power-down sequence is the
following:
1. Drive OE input HIGH to disable the device.
2. Remove power from either VCC.
3. Remove power from other VCC.
