MC74HCT273ADTR2G

The MC74HCT273ADTR2G is a type of logic flip flop, designed for both industrial and consumer applications. It is a cost-effective and efficient device, with performance that outperforms more expensive comparable devices. The HCT logic family provides designers with a single logic family that offers fast switching times, high input and output drive, and very low power consumption.

Application Field

The MC74HCT273ADTR2G is an ideal device for applications such as memory tenancing and sequentially controlling digital circuits and other logical applications. It can also be used for synchronizing digital inputs, including multiplexers and gates, for controlling logical signals. It is also well suited for powering system components such as DRAMs, SRAMs, ROMs, and FIFOs, although this application field requires more advanced devices. Other applications include pattern recognition, Boolean logic, signal/pattern recognition, signal flow control, error detection, and audio signal detection.

Working Principle

The MC74HCT273ADTR2G is an 8-bit register with a latchable output. It is composed of four organized in two packages (quad and dual) and is the smallest register currently available in the HCT series. The latchable input and output enable provides the convenience of storing data while maintaining high-speed operation.The MC74HCT273ADTR2G has an active-low reset enable (REN) pin. This input is used to reset the internal Flip-Flops to their initialized values. There is also an active-high output enable (OE) pin. This input allows users to enable, disable, or reset the data output of the device. When the REN pin is 0, the device is initialized and when it is 1, the Flip-Flops retain their values from the previous clock cycle. When the OE Pin is 1, the data output is enabled and the outputs remain unchanged from the last clock cycle. When the OE Pin is 0, the data output is disabled and the outputs are forced to 0.The MC74HCT273ADTR2G is powered by a +7V to +30V supply. It has a maximum clock frequency of 250 MHz, a setup time of 3ns, and a data hold time of 1ns. It is also available in a variety of package types, such as printed circuit board (PCB), TSSOP (Thin Shrink Small Outline Package), and SOIC (Small Outline Integrated Circuit).The MC74HCT273ADTR2G is ideal for high-speed, low-power applications that require data storage and synchronization capabilities. Its small size, fast switching time, and high input and output drive provide an efficient and cost-effective solution for a wide range of applications.
