HC148-SMD, 8-to-3 Priority Encoder, SMD Package, 2V-6V

The HC148-SMD is a high-speed CMOS priority encoder, designed for logic control and data encoding applications. It features an 8-input to 3-output encoding system, where the highest-priority input determines the binary output. This makes it ideal for systems requiring n-bit encoding, code conversion, and data prioritization. With a wide operating voltage range of 2V to 6V, the HC148-SMD ensures reliable performance in low-power and high-speed logic systems. The device incorporates enable inputs and outputs (EI, EO) for cascading, allowing octal expansion without external circuitry. Its low power consumption and standardized CMOS logic levels make it a suitable choice for power-sensitive embedded systems and digital signal processing applications. The SMD package offers a compact footprint, enabling space-saving designs for modern electronic systems.
