Other Parts Discussed in Thread: SN74LVC08A-Q1, SN74HC08-Q1, SN74ALVC08-Q1, SN74AHC08Q-Q1

At present, we want to reduce costs. We want to replace SN74LVC1G08QDBVRQ1 on board with 2-3 SN74LVC08-Q1 or SN74LVC08A-Q1.

1. Can you help me to determine which one is suitable, or do you have any other recommendations?

2. What is the difference between SN74HC08-Q1 and SN74LVC08A-Q1?

    The difference between the SN74LVC08-Q1 and the SN74LVC08A-Q1 is that only the latter exists.

    If you meant the SN74ALVC08-Q1: its inputs are not 5 V tolerant.

    The HC is slower and has lower drive stength than the (A)LVC. If the HC works in your circuit, consider using the SN74AHC08Q-Q1 instead, which has better characteristic at lower cost.
