CD74AC574M96 Logic - Flip Flops

The CD74AC574 is a hex-buffering enabled register with five-state outputs. Being part of the AC Series of Logic, the CD74AC574M96 offers high speed and low power dissipation in a small package. It has a wide application field, as it is mainly used to control bus lines in fast-switching applications. The output-enable option is useful as it can be used for driving a bus line high or low afterward. Furthermore, the device provides the capability of level-shifting inputs when used with other families of Logic.

The CD74AC574M96 is typically used in applications requiring a large amount of inputs and outputs, such as communication buses, data acquisition systems, digital signal processing and also analog-to-digital or digital-to-analog converters. As a result, the device can be used in a wide range of applications.

The CD74AC574M96 is characterized by its low power consumption, as it dissipates only 120 mW of total power. Furthermore, it is packaged in a small 14-pin Plastic Dual Inline Package that allows the device to be mounted in a limited space.

Working Principle

The CD74AC574M96 is a Hex-buffering enabled register with five-state outputs. Its operation is based on positive-edge triggered Flip Flops with enabling control. Its operation is performed at a fastened speeds, which is ensured by its extremely short propagation delays and a setup time of 15 ns and hold time of 15 ns.

It has six latched inputs, labeled D0 to D5, and an output enable input, labeled EN. The latter allows for the control of the output states. The device has outputs labeled Q0 to Q5. and all outputs are active low. When the output enable input is high, the states of the outputs are dependent upon the state of the inputs. However, when the output enable input is low, all of the outputs are at the high state, regardless of the state of the inputs.

The device also offers five-state outputs. When the output enable input is high and the outputs are disabled, the outputs remain in a high-impedance state, allowing for the expansion of the device. Furthermore, the device can be used for level shifting applications when used with different families of Logic. In order to ensure correct operation of the device, a power-on-reset circuit is integrated and it automatically set the outputs to the high state when power is applied.

Overall, the CD74AC574M96 is a great asset for anyone in need of a high-speed, low power device with multiple inputs and outputs. It has a versatile application field and its low power dissipation allows it to be used in a wide range of systems.
