SN74HC166N / 174N / 175N / 191N / 192N / 194N / 195N DIP-16 Logic ICs – Pack of 5

SN74HC166N / 174N / 175N / 191N / 192N / 194N / 195N DIP-16 Logic ICs – Pack of 5

This listing covers seven essential 74HC series DIP-16 medium-complexity logic ICs – shift registers, flip-flop arrays, and up/down counters that form the backbone of sequential digital circuit design. All devices are high-speed CMOS operating from 2V to 6V, compatible with Arduino, Raspberry Pi, and 5V TTL systems.
