Logic family 74F175SJ provides a high-speed circuit that is used as a logic flip-flop. Derived from the popular 74F00 family TTL chips, this device can be used with a variety of load requirements. As an edge-triggered device, it is especially suitable for digital circuit applications such as four-bit multipliers and shifters.The 74F175SJ contains two SR (Set-Reset) bistable flip-flops and four multiplexers. The flip-flops are edge-triggered, meaning they require a clock pulse to switch the circuit’s input into both its SET and RESET states. One advantage of edge-triggered flip-flops is that it prevents the false triggering of the circuit when there is noise present in the circuit. The device requires a supply voltage between 4.50 and 5.25 volts, and can operate with a maximum clock frequency of 50 MHz.When using alone, the 74F175SJ offers two main flip-flop functions: SET and RESET. The SET input assigns the true state to the output and the RESET input assigns the false state. The output of the flip-flop is set when the clock input is high and the SET input is asserted. The flip-flop is reset when the clock input is high and the RESET input is high. It is important to note that the SET and RESET inputs should not be asserted simultaneously.The multiplexers in the device can be used to operate the flip-flops in serial and parallel modes. In the serial mode, data input is connected to the SET/RESET inputs of the device, allowing for multiple flip-flop operations in series. When used in parallel mode, the multiplexers break up the circuit into two parallel branches, each containing two flip-flops. An important feature of the 74F175SJ is its capability to generate a delayed output. This is done by connecting one of the multiplexers in the circuit to the complementary output of the first flip-flop, thus creating a two-stage delay. This delayed output is useful in situations where a longer period of time before the new logic level is present is required.The 74F175SJ is a reliable device that is widely used in digital circuits due to its low power consumption, wide range of load requirements, and edge-triggered design that prevent false triggering. It can be used as a SR flip-flop, and its multiplexers enables the device to be used in serial and parallel modes, as well as to generate delayed output.
