Power-Up Considerations
DUAL-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES516I – DECEMBER 2003 – REVISED MARCH 2007
A proper power-up sequence always should be followed to avoid excessive supply current, bus contention,
oscillations, or other anomalies. To guard against such power-up problems, take the following precautions:
1. Connect ground before any supply voltage is applied.
2. Power up VCCA.
3. VCCB can be ramped up along with or after VCCA.
