74HC148 8 to 3 Line Priority Decoder DIP-IC

74HC148 8-to-3 Line Priority Decoder DIP-IC

The 74HC148 is an 8-to-3 line priority decoder. It is supplied in a DIP-IC package. This integrated circuit encodes eight data lines into a three-line octal binary output. It employs advanced silicon gate C2 MOS technology. The device exhibits low power consumption. High-speed operation is comparable to LSTTL logic. Inputs are protected with Schottky diodes. Cascading circuitry, including enable input (EI) and enable output (EO), facilitates octal expansion. Data inputs are active at a low logic level.
