Equivalent or alternative models to evaluate

- MIC4422YN non-inverting companion in the same family and PDIP package for designs that need non-inverting logic

- MIC4451 and MIC4452 higher current family options for heavier gates and faster transitions

- TC4421 and TC4422 Microchip single-channel gate drivers commonly used as functional alternatives with similar supply ranges and logic options

- MCP1406 and MCP1407 Microchip 6 A drivers as lower current alternatives where 6 A is sufficient

- IXDN609 Littelfuse IXYS 9 A driver as a potential cross for high current gate drive needs

Always verify pinout, timing, and absolute maximum ratings with the datasheet before substituting. If you need a vetted drop-in replacement or more options, contact our sales team via the Y-IC website for expert guidance and live availability
