Categories: Flip Flops
Quality Control: Learn More
Texas Instruments SN74HCT74D is a dual, independent D-type flip-flop with set and reset capabilities. Each flip-flop features a data input (D), a clock input (CLK), preset (SD), and clear (RD) direct set/reset inputs, and complementary Q and Q outputs. Operation is triggered by a positive edge on the clock input. This device supports a maximum clock frequency of 46 MHz and operates within a supply voltage range of 4.5V to 5.5V. Quiescent current is a low 4 µA. The SN74HCT74D is housed in a 14-SOIC (0.154", 3.90mm width) package, suitable for surface mounting. Typical applications include digital logic, state machines, and buffer registers in industrial control, consumer electronics, and communication systems. Propagation delay is 18ns at 5.5V with a 50pF load.
