Logic - Flip Flops

Flip-flop is a sequential circuit which is capable of storing 1 bit of data and changing its output state based on the inputs. It is used very widely in digital circuits to do operations like timing, counting, frequency division and data storage etc. There are various types of flip-flop constructions available like S-R flip-flop, master-slave J-K flip-flop, TTL flip-flop and integrated circuit flip-flop etc., each technology having its own particular features.

The 74AHCT273BQ is a high performance CMOS logic flip-flop which is quickly becoming popular in many applications due to its low-power design, low-voltage supply and wide range of features. It is fabricated using the advanced version of high speed CMOS logic technology called ‘limited gate’ technology which provides very low power operation with excellent speed performance. It is split into two sections – the synchronous data latch and the asynchronous reset latch.

Application Fields and Working Principle

The 74AHCT273BQ is well-suited for high speed operations. It is commonly used for a variety of different applications, such as D/A conversion, multiplexers, decoders, shift registers, counter circuitry and auto-gain amplifiers. It can also be used in synchronous circuits such as clock and data signals and memory timing.

The 74AHCT273 functions as a D-type flip flop. The inputs are the D and the clock (CLK). The clock is used to control the “latching” of the data so that the flip flop can store one bit at a time. The CLK is normally a low level as this will enable the flip flop to capture the data present on the D input. This data is then stored in the flip flop and is available at the outputs Q and Q*.

The asynchronous set/reset (SET/RST) allows the flip flop to be reset back to the initial state, even if the clock (CLK) is \'low\' level. When the reset input (RST) is high, the Q output will become low and the output Q* will become high. When the set input (SET) is high, the Q output will become high and Q* will become low.

Conclusion

The 74AHCT273BQ is quickly becoming popular in many applications due to its low-power design, low-voltage supply and wide range of features. It is commonly used for a variety of different applications, such as D/A conversion, multiplexers, decoders, shift registers, counter circuitry, synchronous circuits and auto-gain amplifiers. It can also be easily reset, so that the flip flop can be set back to its initial state. All in all, the 74AHCT273BQ is a useful and efficient flip flop suitable for many digital circuits.
