PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | 1A | I | Channel 1 falling edge trigger input when 1B = L; Hold low for other input methods |
| 2 | 1B | I | Channel 1 rising edge trigger input when 1A = H; Hold high for other input methods |
| 3 | 1CLR | I | Channel 1 rising edge trigger when 1A = H and 1B = L; Hold high for other input methods; Can cut pulse length short by driving low during output |
