Hello Ryker,
Ryker She said: Could we connect the pin STEP1 and STEP2 with same frequency signal?
This would mean you'd start and stop the two steppers at the same time as well as run at the same speed or a multiple based on the microstep mode selection…
unfortunately , i do not have any plots for HC132-Q1. I referred a similar device SN74LVC1G132 and found that the lower the temp the lower is the threshold values in general.
Part Number: SN74LVC1G00 We have received a PCN NO- 20260915001.1 from TEXAS INSTRUMENTS , the affected parts are SN74LVC1G00DBVR, SN74LVC1G08DBVRG4, SN74LVC1G08DBVR, SN74LVC1G32DBVR, SN74LVC1G08DBVR, SN74LVC1G125DBVR and SN74LVC1G86DBVR. The change specified…
Other Parts Discussed in Thread: SN74LVC3G17 , SN74LVC1G132 I'm trying to find out if it's recommended to use an SN74LVC3G17 with an RC on the input that will create a rise time of 10ms+. It has a Schmitt input so it should work, but I can't find anything…
Hello Janet,
I propose to use the circuit below for the discharge:
I also noticed that you are using the NAND gate SN74AHC1G00, I would recommend to use the SN74LVC1G132 instead in order to avoid having jitters on your signal CTRL1.
Best regards…

I also note that your AND gates are only driving 3.4V into the LMG5200 which should be ok, but when I look at the RC ramp on the input to U7 around the 50us mark, it looks like the gate output is immediately going high when the input goes high…
