SN74LS74N

SN74LS74N is a dual D-type positive-edge-triggered flip-flop integrated circuit (IC) from the 74LS series (Low-power Schottky TTL). Each IC contains two independent D flip-flops with individual data (D), clock (CLK), preset (PRE), and clear (CLR) inputs and complementary outputs (Q and Q̅).

Key Features:

• Dual D-type flip-flop: Two flip-flops per IC, each operating independently.

• Edge-triggered: Changes state on the rising edge of the clock signal.

• Asynchronous inputs: PRE (preset) and CLR (clear) can override the clocked operation for immediate set or reset.

• Standard TTL logic levels: Compatible with other 74LS series devices.

• Complementary outputs: Q and Q̅ provide both true and inverted outputs.

• Typical applications: Data storage, registers, frequency division, counters, and timing circuits.
