74HC148 DIP 8-Line Priority Encoder IC

Description

The 74HC148 DIP is an 8-to-3 line priority encoder belonging to the 74HC logic family. This high-speed device converts 8 input lines into a 3-bit binary code, with priority encoding ensuring that the highest-priority input (the lowest-numbered active input) is represented in the output. It is commonly used in digital systems to simplify input handling, interrupt management, and signal encoding applications.

Operating within a voltage range of 2V to 6V, the 74HC148 is fully compatible with both TTL and CMOS logic families. It features an active-low enable input and active-low outputs, which allow for easy cascading to encode more than eight inputs. With a fast propagation delay of approximately 16 ns at 5V, this IC ensures efficient and rapid data processing.

The 74HC148 DIP is widely used in priority interrupt handling, digital input reduction, and multiplexing applications. Its efficient logic design and low power consumption make it an essential component for engineers and developers working on microcontroller-based systems and digital logic circuits.
