The SN74LS298DR is an integrated circuit (IC) component manufactured by Texas Instruments. It belongs to the LS family of bipolar TTL logic devices and is specifically designed as an 8-bit shift register with three-state outputs. This IC offers various key features and functions that make it suitable for a wide range of applications.
One of the essential features of the SN74LS298DR is its 8-bit serial-in, parallel-out shift register functionality. It enables the IC to receive serial data on one pin and provide parallel data output on eight pins. The shift register operation allows data to be shifted in one direction (serially) and stored or output in another direction (in parallel).
The IC also includes asynchronous clear and a control pin that allows it to load data in parallel when desired. This control pin helps in controlling the functioning of the shift register.
Another significant aspect of the SN74LS298DR is its three-state output buffers. These buffers provide the flexibility of enabling or disabling the outputs, allowing multiple ICs to be connected together without any contention issues. The three-state outputs enable the IC to be used in bus-oriented systems, where multiple devices can share the same data lines.
The SN74LS298DR operates on a power supply voltage ranging from 4.75V to 5.25V
