SN74LS Series DIP-14 Logic ICs — Dual Flip-Flop & Logic Gates Assortment (5-Pack)

SN74LS Series DIP-14 Logic ICs — Dual Flip-Flop & Logic Gates Assortment (5-Pack)

The SN74LS series are classic TTL (Transistor-Transistor Logic) ICs in DIP-14 through-hole package — the industry-standard logic family used in digital circuit design for decades. This assortment includes dual flip-flop and logic gate variants from the 74LS family, covering sequential and combinational logic functions. Operating from 5V supply with standard TTL input/output levels. Pack of 5 (select variant).

74LS vs 74HC

• 74LS (this IC): TTL, 5V only, higher power, TTL input levels — for legacy TTL circuits
• 74HC: CMOS, 2–6V, lower power, CMOS input levels — for modern 3.3V/5V designs

Typical Applications

• Digital logic circuit design and prototyping
• Sequential logic (flip-flop based counters and registers)
• Combinational logic (gate-based circuits)
• Electronics education — TTL logic fundamentals
• Legacy TTL circuit repair and replacement
