Quiescent current and output drive
Output drive is 4 mA source and 4 mA sink, typical for HCT. That drives one or two standard LSTTL loads directly; for a higher fan-out or a long trace, buffer the output or use a 74ACT variant.

Frequently asked questions
What is the propagation delay of SN74HCT32N?
Maximum propagation delay is 22ns at 5.5V supply with a 50pF load. This is the worst-case figure across temperature and voltage; typical performance is lower.
