8 to 3 Line Priority Encoder IC - 74HC148
The 74HC Series 74HC148 is a 16 Pin 8-Line to 3-Line Priority Encoder IC having 2V to 6V Operating Voltage range with a 5.2mA output current and low power consumption. It encodes Eight Data Lines to a 3-Line Binary. It features priority decoding of the inputs to ensure that only the highest-order data line is encoded. Cascading circuitry (enable input EI and enable output EO) has been provided to allow octal expansion without the need for external circuitry. Data inputs and outputs are active at the low logic level.
