TC74VHCT74AFTEL

Logic - Flip Flops

The TC74VHCT74A family are advanced high-speed CMOS logic devices that combine two D-Type flip-flops with their complementary output (Q bar) in order to implement toggle, latch, pulse, and gated trigger circuits. Due to its small package sizes, and low power consumption, the TC74VHCT74A is suitable for industrial, commercial, and military applications.

Application Fields

The TC74VHCT74A has many uses and applications. It can be used as a counter, latch, a frequency divider, in waveform shaping and modulation, as well as in digital-to-analog and analog-to-digital conversion. It is also commonly used in microprocessors and memory devices.

Working Principle

The TC74VHCT74A operates by implementing two D-type flip-flops with their complementary outputs (Q bar). When enabled, each Flip-Flop dynamically stores or re-stores the input data for one complete clock cycle. The two Flip-Flops are configured either in master-slave or master-invalid configurations, or set and reset configurations for various applications. The output is determined by the logic level of the input data and the state of the clock signal. When the clock signal is LOW, the data is stored and the output remains unchanged. When the clock signal is HIGH, the data is NOT stored and the output may change because it depends on the state of the individual data input signals.

Conclusion

The TC74VHCT74A is an advanced high-speed CMOS logic device with many uses and applications. It can be used for many applications such as frequency division, waveform shaping and modulation, or digital-to-analog and analog-to-digital conversion. It operates by implementing two D-type flip-flops with their complementary outputs. When enabled, each Flip-Flop dynamically stores or re-stores the input data for one complete clock cycle. Thus, it can be used as a counter, latch, or a frequency divider.
