Other Parts Discussed in Thread: ESDS314, SN74HC125
Hello Community,
We have a application where we want to interface the output of SN74HCS125 operating at 5V VCC to the MCU digital input pins which are 5V tolerant. The signal shall be from external PWM generator upto 4kHz maximum.
- I want to confirm do I need to add any current limiting resistor between the output of SN74HCS125 & the inputs of the MCU?
- The total trace length between the MCU & the buffer output pins shall be less than 4"
Kindly suggest the robust measures to implement this use case.
Regards
