Logic - Flip Flops are digital components or circuits used for storing data. Integrated circuit implementations for their logic functions, such as the SN74AHC273PWR, have been developed to allow high speed, low cost and low power operation.

The SN74AHC273PWR is a high speed low power octal D-type positive edge-triggered flip-flop integrated circuit. It features two-level output drivers and also has a arbitration logic. Manufactured in CMOS logic, the SN74AHC273PWR is available in several package types such as SOIC, SSOP, and TSSOP.

The SN74AHC273PWR mainly finds application in digital signal processing systems, embedded controllers, automotive control systems and other applications comprised of logic functions. Its arbitration logic enables the device to function as an arbitrator and therefore adds to its usability. The device has eight D-type flip-flop, which allows for easy synchronization of data as well as for parallel data transmission.

The SN74AHC273PWR has two distinct inputs, the Clock(CLK) and the data (D)inputs. When the Clock is high the flip-flops transfer the data at their inputs to their outputs, in other words, the data at the D-inputs can be transferred (or clocked) to the Q-outputs. The clock pulse must be at a low voltage for set-up and hold times as defined, however, the flip-flop will safely be in the set-up and hold mode with Clock at voltage levels above and below the Vcc and ground.

The two Q-outputs (Q1 and Q2) alternate in relationship to the CLK signal. An input signal to the clock will cause a rise in the clock and consequently a change of state of the outputs. The SN74AHC273PWR has two arbitration logic circuits, the first is the Schmitt trigger, which is used to clean the clock signal, enhance noise immunity and reduce crosstalk between adjacent pins. The second is the Logic 1 Hold (L1H) feature which will hold the outputs of the flip-flops when the Clock signal is low and the Data signal is high.

The SN74AHC273PWR is a low cost, low power, high-speed 8-bit OCTAL D-type Clear Positive Edge-Triggered Flip-Flops integrated circuit. It is suitable for a variety of logic applications and ideal for automotive, digital signal processing and embedded systems. The flip-flop is designed to provide a high degree of noise immunity and is also protected against accidental brown-outs and other system transients. Its two arbitration logic circuits also provide great flexibility, allowing designers to easily implement logic functions in their designs.
