TTL 7476

TTL 7476 is a dual JK flip-flop

integrated circuit (IC) that is part of the 7400 series of digital logic chips. It contains two independent JK flip-flops, each with a clock input (CLK), a clear input (CLR), a set input (SET), and complementary outputs (Q and Q'). The JK flip-flops can be triggered on either the rising or falling edge of the clock signal, depending on the state of the J and K inputs. When both J and K inputs are low, the flip-flop maintains its previous state. When J and K are both high, the flip-flop toggles between its two states on each clock edge. The CLR input resets the flip-flop to a low state, while the SET input sets it to a high state. The 7476 chip is commonly used in digital circuits such as counters, registers, and shift registers.
