SN74ABT574ADWR Application Field and Working Principle

Logic - Flip Flops

The SN74ABT574ADWR is a quadruple positive edge-triggered ‘D-type’ flip flop with a common clock (CP) and an asynchronous clear (ACLR) input used in logic applications to control the flow of data. This power efficient device is manufactured by Texas Instruments and is available in a 16-pin TSSOP (Thin Shrink Small Outline Package).

The SN74ABT574ADWR is a type of bistable flip flop where the output can exist in any of two states. The device contains four flip flops that are triggered by a common clock (CP) inputs, the levels of which are represented by the labelled output Q. A toggle switch like action occurs from one state to the other when triggered by the clock. The device also has asynchronous clear (ACLR) controls which when set to low level or ground, will reset the output of each flip flop to a logical low or ground, and enable it into the reset state.

The SN74ABT574ADWR can be used in a variety of circuits where a flip flop configuration is needed, such as power control circuits, timing circuits, counters, and logic level control circuits. The device also contains a set of four bidirectional data lines functioning as both input and output, which allows the transfer of data to and from the device. Furthermore, the device can also be used in a shift register circuit.[1] Due to the variety of applications it can be used in, the SN74ABT574CDWR is a versatile device.

Working Principle

The output of the flip flop is a combination of an input signal and the current state of the device. When the input signal CLK is pulsed high, the device transitions from one state to the other. SN74ABT574ADWR maintain their current output states until the next CLK edge is detected. The device has four bidirectional data lines that function as both input and output. Each of the input lines allow for data to be transferred into the flip flop. The output data lines enable data to be retrieved from the device. The device also contains an asynchronous clear input ACLR that when set to low level or ground, it sets the outputs of each flip flop to low, enabling them into the reset state.

Limitations

The SN74ABT574ADWR device has the limitation of being vulnerable to noise and glitches when the input signals change rapidly. Also, the AC slew rate of the device should not exceed 80ns, with a maximum input voltage range of -0.5V to 7V. The output of the device is intended to switch from one state to the other at very high speeds, and thus has a rise time of approximately 6ns, and a fall time of about 3.4ns.

Conclusion

The SN74ABT574ADWR is a quadruple edge-triggered ‘D-type’ flip flop with a common clock input and asynchronous clear (ACLR) controls which can be used in various electronic circuits. Its versatile design makes it suitable for a detailed application such as logic level control circuits, counters and shift registers. The device has the limitation of being susceptible to noise and glitches when input signals change rapidly. This can be addressed by controlling the slew rate and keeping the input voltage range as required.
