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 0V, outputs are in a
HIGH-Impedance state. To ensure that bus contention,
excessive currents, or oscillations do not occur, a proper
power-up sequence is recommended.
The recommended power-up sequence is the following:
1. Apply power to either VCC.
2. Apply power to the T/R input (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.
The recommended power-down sequence is the follow-
ing:
1. Remove power from either VCC.
2. Remove power from other VCC.
