Overview
The 74HCT147D,652 is a 10-4 priority encoder integrated circuit manufactured by NXP USA Inc. This device is part of the 74HCT series, which is known for its high-speed CMOS technology and compatibility with low power Schottky TTL (LSTTL) logic. The 74HCT147D,652 encodes nine active LOW inputs into a four-bit binary representation, with a priority assigned to each input. This ensures that when multiple inputs are active, the input with the highest priority is represented on the output.
