SN74AVC1T45: We observed a glitch on port A when VCCB is in start up

Part Number: SN74AVC1T45
Other Parts Discussed in Thread: SN74AXC1T45

Hi TI teams,

For SN74AVC1T45, I deployed below design and there is a pull down resistor on port B. In the design, VCCA will be powered up first, and we observe a glitch on port A when VCCB is in soft-start. Could you help this? and could you clarify the reason?
