Hi Parviz,
Welcome to the E2E Forums.
Just to give you a couple quick tips before I get directly to your question:
The Logic Forum has a Frequently Asked Questions section that often helps out, located here:
Also, we have recently started releasing…
Kamesh,
The SN74AVC1T45 IBIS model is below:

The SN74AVC2T45 IBIS model is below:

Let me know if this is ok. Thanks.
Best Regards,

Hi,
SN74AVC1T45 may meet your requirement. This part supports level translation between any of the 1.8V, 3.3V and 2.5V. However, if signal translate to 2.5V, the max data rate is 320Mbps at 15pF load. When transfer signal is clock, the max clock frequency…
na na78,
I do not think that CL loading will damage the device. It will limit the maximum data rate supported by the SN74AVC1T45, since it will take a longer time to charge and discharge a larger capacitive load.
Do you have a schematic that you…
Dear Iain Hunter,
I have gone through the mentioned hardware signals. I am able to see the VBAT and VIO in scope but not able to see the SCLK and WL EN. One more information, we are using Level shifter in our custom board design. The level shifter chip…
At 200 MHz, there isn't an auto-bidirectional translation solution. There is, however, a direction controlled solution in the SN74AVC2T45 (500 Mbps / 250 MHz clock max)
It's my understanding that only the clock signal operates at 200 MHz. If that's…
The push button its function is to connect two points electrically ( Supposed to be as same as the tweezer when we use it) and must be applied to SN74AVC1T45 pin 4 and VRTC_1V8 as in the attach schematic and as a result the MAIN_ON_OFF_SW ( GPIO) go to…
Lakshmi,
I'm not sure what other information you are asking me to provide. The SN74CB3T3257 recommended operating conditions states it can pass signals from 0 to 5.5 V, the supply voltage can be 2.3-3.6 V, and the logic control signals must be >2V…
Other Parts Discussed in Thread: SN74AVC1T45 , SN74AVC4T234 Hello,
This question may be already answered on this forum, but I haven't seen it: On the SN74AVC1T45 datasheet, there is two information that seems not fitting together:
1) Page 2: "This…
Hi, Atthen,
For the I max calculation, here is the formula to calculate it.
I_total = I_dynamic + I_static
For I_static, you can find the value in the datasheet.
I_dynamic = (Cpd+Cload) x Vcc x freq. For Cpd, please check with the Datasheet…
