The TI E2E™ design support forums will undergo maintenance from July 11 to July 13. If you need design support during this time, open a new support request with our customer support center.
Overshoots of this magnitude are likely to be measurement artifacts, usually caused by a long ground lead. Please show a photograph of your test setup.
AHC devices have weaker output drivers. There is no exact replacement, but the SN74AHCT245 can put…
Hey Jigar,
Glad I could be of help.
There are really two good methods of converting a unidirectional logic signal from 3.3V to 5V that I know of.
The first is what Clemens recommended - and it's certainly an easy and good solution. You can use any TTL…
Part Number: TMS320F28377D Other Parts Discussed in Thread: SN74AHCT245 , SN74HCT245 What is the output current of TMS320F28377DZWT as PWM output GPIO port (gpio145-gpio168)?What is the resistance between SN74AHCT245 and PWM back end?What is the resistance…
I need to use the GPIO 145-gpio168 of TMS320F28377DZWT to drive IGBT, but the driving capacity of GPIO itself is too small and needs to be enhanced and expanded.The signal cannot be input into the PWM pin, and the TTL level can be directly converted to…
Hello,
Assuming you have a 5V supply connected to VCC, a 3.3V signal on the input is considered HIGH.
This is a TTL compatible device, which means that the inputs interpret voltages greater than 2V as an input HIGH, and voltages less than 0.8V as an…
