One catch: it is RoHS non-compliant, which means it contains lead in the solder finish — fine for military, aerospace, or industrial BOMs that have a RoHS exemption, but a blocker for consumer electronics bound for EU markets. The PC suffix indicates a plastic DIP package, through-hole mount, which mates with standard DIP sockets or wave-solder pads.","metaTitle":"74LS298PC TTL Multiplexer, 4-Func 2-Line Input, Active","metaDescription":"74LS298PC is a TTL multiplexer with 4 functions and 2 line inputs.

Used for data selection, bus routing, and signal gating in 5 V TTL logic circuits."},{"question":"What is the closest functional second-source for the 74LS298PC?","answer":"The DS90CP22MT/NOPB is a different device class — a crosspoint switch, not a TTL multiplexer — and is not a pin-compatible or functional replacement. No direct second-source is listed in the available records. Stick with the 74LS298PC or evaluate other 74LS-family multiplexers for a drop-in fit."},{"question":"What does the PC suffix mean on the 74LS298PC?","answer":"The PC suffix typically indicates a plastic dual-in-line package (PDIP) for through-hole mounting. The Bulk packaging means it ships loose, not on tape and reel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74LS298PC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74LS298PC when reusing this data.
