74hc132d with what type of replacement, motherboard boot circuit is broken?

74HC132 is a 4 2 input and not gate (Schmidt input). What model can be used to replace it depends on the specific circuit.

For example, all logic devices in the original circuit are TTL circuits, then 74HCT132D can also be used, if the original circuit operating voltage in the range of 2V~5.5V, 74AHC132D can also be used. There are also many Schmidt input and not gate is only a slight difference in operating voltage and speed, the pins are compatible with 74HC132, such as 74VHC132, 74AC132, 74LVX132, etc., even 74HC00 is not absolutely can not be replaced, it is also compatible with 74HC132 pin, the difference is only not Schmidt input. So everything depends on the actual circuit.
