11 Power Supply Recommendations

The SN74AVC1T45 device uses two separate configurable power-supply rails, VCCA and VCCB. VCCA accepts any supply voltage from 1.2 V to 3.6 V and VCCB accepts any supply voltage from 1.2 V to 3.6 V. The A port and B port are designed to track VCCA and VCCB respectively allowing for low-voltage, bidirectional translation between any of the 1.2-V, 1.5 -V, 1.8-V, and 3.3-V voltage nodes.

11.1 Power-Up Considerations

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.
