It encodes ten active-low inputs into a four-bit binary output, asserting the highest-priority active line — a standard function for interrupt management in processor-based systems or for reducing parallel data bus wiring. ## Supply and temperature envelope Output drive is rated 5.2 mA source and 5.2 mA sink at the rated supply — enough to drive a standard CMOS logic input or a low-power LED indicator, but not a heavy bus. For a longer fan-out, buffer the outputs. ## Production status and compliance It is fully ROHS3 compliant — no exemptions expiring — so it passes the environmental requirements for EU-market builds without a waiver.","metaTitle":"TI CD74HC147PWT Priority Encoder, 1x10:4, 16-TSSOP","metaDescription":"Texas Instruments CD74HC147PWT 74HC priority encoder, 1 x 10:4 circuit, 2V-6V supply, -55°C to 125°C, 16-TSSOP.
