| Description | 8-Line to 3-Line Priority Encoder, High-Speed CMOS, 2V-6V, Inverting Output, SOIC-16 Package |
Product Overview
The SN74HC148DR is a high-speed CMOS 8-line to 3-line priority encoder designed for digital priority encoding applications. It accepts eight active-low input lines and encodes the highest-priority active input into a 3-bit binary output code, featuring built-in priority resolution to ensure dominant input signals are processed first. The device operates over a wide 2V to 6V supply voltage range with low power consumption, high noise immunity, and fast switching speed, compatible with standard HC CMOS logic families. It includes enable input and expandable output features for cascading multiple devices to support larger encoding systems. Housed in a compact SOIC-16 surface-mount package, it provides reliable performance for digital control, interrupt systems, and input encoding in industrial and consumer electronics.
