Dear TI experts,

General-purpose logic ICs
Specifically
SN74LVC244APWR
SN74LVT244BPW
Are there any documents on input voltage relaxation conditions?

I would like to know the input allowable voltage for overshoot/undershoot…

Hi Sirs

When OE pull high, the impedance of output (Y side) is high, how about the input side?

We want to know in this condition, impedance of A side is high impedance or low impedance, or floating?  

Thank you

Hello,

Should I connect GND to the Thermal Pad of SN74LVC244ARGY?
This is not mentioned in the datasheet, so please let me know.

Hi,

I need to use SPI master/slave configuration, have one STM32 as master uC as SPI master & 6 STM32 are slaves, i was trying on one prototype which involved external wiring…

Hi TI Team.

Is there any problem if voltage is applied to Vin (A side) before voltage is applied to VCC in this IC?

Best regards.

Hello expert,

Are we able to enhance output driving capability in SN74LVC244APWR IBIS model? Based on datasheet, output driving capability is related to VCC. Could we adjust VCC in IBIS model? If no, do we have other method to…

Hi,

Please see below queries and request you to suggest

Query1: Regarding 8 Bit Buffer IC SN74LVC244ARGYR…

Hi,

RnD currently used SN74LVC244A for the signal 50MHz. The output signal is distortion. 

Is there solution for high speed (tpd < 5.9ns)?

Thanks and Best regards,

Hello,

I didn't find information about the connection of thermal pad (21). 

Is the pad isolated from GND ?

SN74LVC244ARWPR

Package X1QFN (RWP)

Thanks.

Hello　E2ETeams

Ask a question.

Do you use barrier metal for your SN74LVC244APWR?

Hi team,

I would like to use SN74LVC244A to divide the output of one oscillator into four outputs as shown below.

In this condition, do you have any information about the output jitter characteristics of SN74LVC244A?

If there…

Hi Team,

Do we have recommendations for a Buffer IC that is shorter in height than the SN74LVC541's VQFN (H=1.0mm) package?

Best regards,

Hi，

Will this dip/step at the edge be concern? I think the time is short and should not cause an additional pulse and influence the following device. 

Could you help confirm?

I got the Ibis model for SN74LVC244A, but in that package I couldn't see SN74LVC244ARWPR (Which is having X1QFN Package)

Hello,

What is the difference between SN74LVCH244APWR and SN74LVC244APWR? I only see an additional package of the SN74LVC244APWR, but don't see differences otherwise. Could you please share any other differences?

Thank you,

Hello team,

• What is the maximum supported data rate for SN74LVC244A?
• What would be the min and max of tw?

              (I see tw on datasheet, but doesn't specify any numbers.)

Best Regards,

Hello TI Experts,

 We have a faulty design (which have already been mass shipped out in field ….), we want to evaluate the risk of the design and consider next step

Conditions:
1.  SN74LVC244APWR

2. 3.3V power supply
3. Two not…

I want to generate a pulse that always falls between 20ns and 50ns over the entire temperature range of an industrial device.  Is 20ns a feasible lower bound for this device?  I have…

Hi Team,

When I look the Vo spec in the datasheet of SN74AHCT244 & SN74LVC244A, I found something different. In the DS of SN74LVC244A, the Vo max has different description in power…
