HLF 74LS148 8-to-3 Line Priority Encoder – SOP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Surface-Mount Package

The HLF 74LS148 SOP16 is a Low-Power Schottky TTL 8-to-3 priority encoder IC that encodes eight active-low inputs into a 3-bit binary output, prioritizing the highest-order input when multiple inputs are active. It includes enable inputs/outputs for cascading, allowing expanded priority encoding across multiple devices.

Operating between 4.75V and 5.25V, the SOP16 surface-mount package ensures compact design, low power consumption, and high-speed TTL operation—ideal for space-constrained embedded, industrial, and digital systems.
