Part Number: SN74LXC1T45-Q1 The datasheet has several sections that seem to be contradictory regarding the I/O lines. The control lines (DIR) have specific instructions to not leave floating. Is it acceptable to leave buffer inputs floating?

Part Number: SN74LXC1T45-Q1 I have a PCB with a few SN74LXC1T45QDRYRQ1placed on it. And I am relatively sure that my manufacturer has placed them backwards. The issue is that it's very hard to confirm visually what way around the part is. The datasheet…
Part Number: SN74LXC1T45-Q1 Hi,
Can you explain what this table means from the datasheet?
My understanding is that for the DIR pin, VT+ gives the voltage range of a logic high (A to B) and VT- gives the voltage range of a logic low (B to A). But…
Part Number: SN74LXC1T45-Q1 Other Parts Discussed in Thread: AVCLVCDIRCNTRL-EVM , Hi,
In my current design I have a 3.3V source connected to VCCA and a voltage divider network connected to A that's roughly 3.3V. What is the pull down resistance on…
Hello Ethan,
Thanks for the clarification. Here's my updated list:
For RGMII, SN74LXC8T245-Q1.
For MDC/MDIO, LSF0102-Q1
We don't have an auto-sensing buffer like TXB0101 that's qualified for automotive. Would a bi-directional level translator…
The rise time violates the Δt/Δv limit. I do not know whether this is the cause of the problem, but you are certainly running the device outside its recommended operating conditions, and you are likely to get oscillations at the output. Use the SN74LXC1T45…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 , SN74LXC1T45 5Vと3.3Vの双方向レベル変換に「TCA3-Q3」を使用することを検討しています。プルダウン抵抗を3.3Vシステム入出力端子に挿入し、プルアップ抵抗を5Vシステム入出力端子に挿入します。電源投入時にローレベル(0V)に設定したいのですが。質問は次のとおりです: 1. 「TCA9517-Q1」の使用に問題はありますか? 2. プルダウン抵抗値の計算方法を教えてください…
