Logic - Flip Flops

The N74F273AD,623 is a dual D-type flip-flop connected to two synchronous edge-triggered resets which are active-low and active-high logic levels. It is commonly used in logic circuits due to its simplicity, reliable operations, and consistent outputs. The N74F273AD,623 provides an input edge-triggered data latches with asynchronous reset capability. This flip-flop is internally designed to switch data between your input and output in one clock edge, which makes it an efficient choice for many digital applications.

Application and Working Principle of N74F273

The N74F273 can be used in numerous applications. It can be found in digital logic circuits and logic designs, as well as used in analog-to-digital converter designs. This particular type of flip-flop has become a favorite device in logic designers as it provides very low propagation delay, is independent of clock frequency, and is immune to race conditions. Moreover, the synchronized data input and output makes this flip-flop more reliable than other forms of logic device.

The working principle of the N74F273 flip-flop is quite simple. When there is a rising edge on D_n-1, the data input latch is enabled and the data is held at the D_n-1 input. The rising edge on CLK_n-1 triggers the flip-flop and drives the flip-flop to a new state. If the new state is opposite of the previous state, then the rising edge is captured and the data held at the Q output is clocked to the data input latch. If the rising edge is the same as the previous state, then the output is not changing and the input will not be clocked. This four-stage data latched process is the working principle of the N74F273 flip-flop.

Features of N74F272

The N74F272 features rail-to-rail data capture, high noise immunity, high speed, low skew, and low propagation delay. It is available in several package options including SOIC-14, TSSOP-14, and TQFP-20W. Its operating voltage is 2.0V, the maximum power dissipation is 1.0W, and the maximum operating temperature is 85°C.

Conclusion

The N74F273AD,623 is a dual D-type flip-flop, widely used in logic applications due to its low propagation delay, high noise immunity, high speed, low skew and low propagation delay. The flip-flop is designed with two synchronous edge-triggered resets, and its output is held at a steady state until it is clocked to switch states. This makes it ideal for many digital applications, as it ensures reliable operations and consistent outputs.
