74HC02D is a commonly used driver chip that is commonly used to drive devices such as motors and lights. If you want to use other chips to replace 74HC02D, then you need to choose the right chip according to your specific application scenario and requirements. Here are some chips that can be used to replace 74HC02D:
1. 74HC05: This is a high level driver chip similar to 74HC02D, which can be used to drive LED and motor applications.
2. 74LS02: This is a dual channel NPN transistor chip that can be used to drive LED and motor applications.
3. 74LS04: This is a dual channel PNP transistor chip that can be used to drive LED and motor applications.
4.74HC04: This is a four-way driver chip that can be used to drive LED and motor applications.
All of these chips can be used to replace 74HC02D, but the specific choice of chip depends on your application scenario and requirements. If you're not sure which chip to choose, consider consulting a chip manufacturer or circuit designer.
74HC02D is a four-gate and non-gate integrated circuit chip. If you need to replace it, you can consider using other four-gate and non-gate chips with the same function, such as SN74HC02N, CD74HC02E, etc. These chips are functionally similar to 74HC02D, but there may be some subtle differences, you can choose the appropriate replacement chip according to the actual needs.
74hc02d can be replaced by CH4001, they both are
Four sets of 2 input or non-gate circuit chips, logic function
Same, and both are two-column 14-pin packages
