Visão Geral
Description
Each flip-flop within the SN74HC74PWR has a data (D) input, a clock (CLK) input, set (SD) and reset (RD) inputs, as well as complementary outputs (Q and Q̅). Data is transferred to the output on the rising edge of the clock signal, making it edge-triggered. The device is characterized by fast switching speeds, with a typical propagation delay of 13 ns, and operates within a voltage range of 2V to 6V.
The SN74HC74PWR is housed in a TSSOP-14 package, making it suitable for applications with limited space. It is widely used in applications such as data latching, data synchronization, and state machine design within digital systems.
