SN74HC148NSR TI Signal Switches, Multiplexers, Decoders

This 8-line to 3-line priority encoder from Texas Instruments operates from 2V to 6V with typical propagation delay of 12ns, converting eight active-low inputs into a 3-bit binary output. For selection, it features a priority scheme where higher-numbered inputs take precedence, plus an enable input and two enable outputs for cascading. In application, it excels in interrupt controller circuits in MCU-based systems, keypad encoding in smart home keypads, input prioritization in industrial PLC modules, and flag logic in automotive body control modules. It is also widely used in robotics control boards, vending machine controllers, and any system requiring multiple interrupt sources to be condensed into a few microcontroller pins.
