LA5623M
Notes:
1. The minimum supply voltage such that a low-level output can be maintained.
2. Manual reset.
A high level applied to the manual reset pin sets the output 2 pin low, and a low level sets the output 2 pin high.
Pin Assignment
*
1: Ct0
*
2: Ct1
The delay time is 100 ms when
the above two pins are both
left open.
