DRV8434: DRV8434 M0/M1 Control, 74LV06 or 74LV244A Output Hi-Z

Part Number: DRV8434

We want to use the 74LV06 or 74LV244A to driving DRV8434 M0/M1 Pin.

(from 74LV06 or 74LV244A output Hi/Lo/Hi-Z)

When 74LV06 or 74LV244A output Hi-Z , may be a small current to DRV8434 M0/M1.

Will this make DRV8434 misjudgment?
( We need control Drv8434 to 1/2, 1/4, 1/8, and 1/16 Step mode)

  • Hello, KG:

    The M1 pin pulldown resistor is 200kohm; the pullup current is 10uA. What is the 74LV244A and 74LV06 output current in its high impedance around 2V?

    BTW, I saw Cherry asked the similar question.
