The SN74HC148D is an integrated circuit (IC) component used in electronic devices for priority encoding. It is a 8-Line to 3-Line Priority Encoder manufactured by Texas Instruments. Let's explore its key features and overview.
Overview:
The SN74HC148D is designed to encode eight active-low inputs (A0 to A7) into a 3-bit binary output (Y0 to Y2). The priority encoder is a crucial component in digital systems that need to process multiple input signals and detect the highest priority signal. It finds applications in systems like data acquisition, digital signal processing, and communication systems.
Key Features:
1. 8-Line Input: The SN74HC148D has eight inputs (A0 to A7) that can be driven high or low to represent different states or signals. These inputs are encoded into a 3-bit output.
2. Active-Low Inputs: The inputs (A0 to A7) are active-low, meaning that a low signal activates the input, while a high signal deactivates it. This allows for signal prioritization based on the lowest activated input.
3. 3-Bit Binary Output: The IC encodes the active inputs into a 3-bit binary output (Y0 to Y2). These output lines represent the priority of the active input, with Y0 having the highest priority and Y2 the lowest
