Logic - Flip Flops

Flip flop is a basic logic circuit building block, consisting of two stable states and used in electronic logic systems. Flip flops are widely used in the design of digital electronic circuits and are used for creating a range of Boolean logic functions, including gates and memory. The SN74LS73ADR is a kind of flip flop device.

Application field of SN74LS73ADR

The SN74LS73ADR is a type of dual D-type Positive Edge-Triggered flip flop. Applications include multiplexers, register files, and counters. It is mostly used for dividing the frequency of a signal orCreating two signals at different phase levels. In addition, this device is widely used in various applications such as analogue/digital conversion, pulse-code modulation, finite-state machine notation, and serial-to-parallel conversion.

Working Principle of SN74LS73ADR

The SN74LS73ADR is a dual positive-edge triggered flip flop consisting of two D-type flip flops sharing a common Clock (CP) input. Each flip flop contains two inputs, Data (D) and Clock (CP). The device will recognize the positive-going edges at CP and load the data present at their respective D inputs into the flip flop. The data will be stored until a falling edge of CP is encountered and the device will recognize and responds to this next rising edge of CP. This device will accept logical signals from either TTL or CMOS logic families.

The device also includes a Reset (R) input which resets both flip flops when it is connected to a high voltage level. The R input can be inverted to get the inverse reset (R\') feature. Outputs of both flip flops are available which can be used independently or in combination.

Conclusion

The SN74LS73ADR is a dual D-type positive edge-triggered flip flop which has a wide range of applications such as in frequency dividers, multiplexers, and counters. This device also has a reset input to reset both flip flops when a high voltage is present. The SN74LS73ADR falls into the group of logic - Flip Flops.
