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 V
a high-impedance state. The control input (OE) is
designed to track the VccA supply. A pull-down resistor
tying OE to GND should be used to ensure that bus con-
tention, excessive currents, or oscillations do not occur
during power-up/power-down. The size of the pull-down
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 V
2. Apply power to the second V
3. Drive the OE input high to enable the device.
The recommended power-down sequence is the
following:
1. Drive OE input low to disable the device.
2. Remove power from either V
3. Remove power from other V
