SN74LVC373ADW Application Field and Working Principle

The SN74LVC373ADW from Texas Instruments is a Latches designed for usage in high-speed logic systems. It is a dual input positive edge-triggered D-type flip-flop that uses D-inputs to control the latch’s state. The SN74LVC373ADW is part of the High Performance Logic (HPL) product range and is capable of operation with both 2.7V and 5V supply.

Features

The SN74LVC373ADW is a low-power, dual-input, latched device. It is designed to offer increased noise immunity and improved logic levels. It is offered in two different packages with two different inputs, 3-STATE or standard. It includes three separate power pins, which allows the device to run on dual supply rails. It has an improved noise immunity over other similar devices and is also more tolerant of hot-socketing.

Applications

The SN74LVC373ADW is primarily used in applications where latch performance is needed from low voltage sources. It is used in applications such as nonvolatile memory systems, logic-level translation and logic-level shifting. The device can also be used in applications requiring logic level translation between logic levels as low as 1.2V and 5V. It is suitable for use in security systems, low-voltage systems and motor control systems.

Working Principle

The SN74LVC373ADW is based on a pulse sensitive D-type flip-flop. The latched behaviour of the SN74LVC373ADW is determined by the input signals applied to the D-inputs. When the positive edge of the clock signal is received, the \'D\' value is written to the output of the latch. On the negative edge of the clock pulse, the output remains in the latched state until the \'D\' input is changed.The SN74LVC373ADW is designed for low voltage operation. This allows it to be used with a variety of low voltage sources such as 2.7V and 5V. The device has three separate power pins allowing it to be used with dual power-rails which is useful in applications where logic-level translation is needed. The device also offers improved noise immunity over other similar devices and is also more tolerant of hot-socketing.

Conclusion

The SN74LVC373ADW is a low-power, high-performance, dual input, latched device. It is designed to offer increased noise immunity and improved logic levels. It is ideally suited for use in applications requiring logic level translation between logic levels as low as 1.2V and 5V. It is used in applications such as nonvolatile memory systems, logic-level translation and logic-level shifting.
