Product details

74LS298PC — TTL multiplexer, 4-function 2-line input

The 74LS298PC is a TTL multiplexer, 4-function 2-line-input device.

Lifecycle and compliance

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.

Package and handling

The PC suffix indicates a plastic DIP package, through-hole mount, which mates with standard DIP sockets or wave-solder pads.

Frequently asked questions

What is the 74LS298PC used for?

It is a TTL multiplexer with 4 functions and 2 line inputs — it selects one of two digital input lines per function and routes the chosen signal to the output. Used for data selection, bus routing, and signal gating in 5 V TTL logic circuits.

What is the closest functional second-source for the 74LS298PC?

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.

What does the PC suffix mean on the 74LS298PC?

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.
