Part Number: SN74AHC245 Other Parts Discussed in Thread: SN74AHC74 Hi team,
Can you provide the recommended max BW of SN74AHC245?
Or can you provide me the related calculation that you could calculate the max BW? I think it's related to tr and tf.…
Part Number: SN74AHC245 Hi Team,
I want to check the tPLH and tPHL parameters in datasheet. I find below table in datasheet. It seems like that the parameters is related to Vcc and Cload on PCB trace.
Below is our measurement. We measure the SN74AHC245…
These signals violate the setup and hold times specified in section 7.6 of the datasheet.
What is the purpose of using a flip-flop in this circuit? Why are you mentioning the '245 transceiver? It's possible that that device, or a transparent latch like…
Part Number: SN74AHC245Q Other Parts Discussed in Thread: SN74AHC245-Q1 , Hi team
In addition to the package option, could you help give the difference between SN74AHC245Q and SN74AHC245-Q1?
Thank you.
Part Number: SN74AHC245 Other Parts Discussed in Thread: SN74AHC541 Hi Team,
In datasheet, I only find the recommended operating voltage(OE/DIR) is 0-5.5?
May I know the recommended operating Vin(signal)? 0V-7V? or it's the same as 0-5.5 like OE/DIR?…
Hi Roy,
The HC family of logic also has clamp diodes and will not resolve this issue.
Perhaps an illustration will be of some help.
Each transceiver device has both input and output structures connected to the pin. When you try to drive the output of…
Part Number: SN74AHC245 Other Parts Discussed in Thread: SN74LVC8T245 Dear colleague,
The customer is asking whether SN74AHC245 supports hot swap?
Thanks a lot!
Best Regards,

Part Number: SN74AHC245 Other Parts Discussed in Thread: SN74HC245 , Hi Team,
My customer would like change their solution from SN74HC245 to SN74AHC245 because Vsignal may larger than Vin.
And below are the questions that we would like to check.
1. Could…
Part Number: SN74AHC245 Hi team,
I have some questions on the schematic of SN74AHC245PWR datasheet.
Are there any diodes inside of IC between input and power?
Are there any protestation inside of IC? Or need to restrict the input current?
If none of …
Part Number: SN74AHC245 Please tell us the cause of the power supply potential rise.
An experiment was performed using 74AHC245 under the following conditions. VCC = DIR = 3.3V. / OE = 0V. A1 = 5V.
The stabilized power supply used for the IC power supply…
