LMH1983: INIT Min pulse

Part Number: LMH1983

Tool/software:

Hi All,

I have a question about the INIT terminal of the LMH1983.
Is there a limit to the pulse width of the signal input to the INIT terminal? Please tell me the minimum pulse.
Also, if you have a timing chart, please let me know.

Best Regards,
Ishiwata

Hi Ishiwata,

Expect a response on Monday.

Hi Ishiwata-san,

LMH1983 requires a rising edge at INIT pin, the duration of staying at HIGH level should not be matter. I guess nanosecond pulse is acceptable. To play safe, I suggest a pulse width of 1µs.
