Tool/software:
Hi Guys
I made schematic with SN74LVCH16T245 as shown below but it does't work at all.
In the schematic, signals related to PWM such as PWM1_1, PWM1_1N, etc are provided from MCU and the signals are high or low level by MCU with normal.
However, the A-side of SN74LVCH16T245 are always low(0[V]) when NPWM_ENABLE_1 and NPWM_ENABLE_2 are connected to 0[V].
So, I removed AR1, AR2, and AR3 but the A-side of SN74LVCH16T245 are always 0[V] regardless of high or low B-side of SN74LVCH16T245.
I can't understand why the A-side of SN74LVCH16T245 are always low(0[V]).
Could you help me my serious problem?
Thank you in advance for your help.
