It selects one of several data inputs and routes it to a single output, a common function in bus-oriented systems, address decoding, or signal routing on a board that needs to share a line among multiple sources. The LS (Low-Power Schottky) process gives it a speed-power tradeoff that sits between the older 54S and the later 54HC families — faster than standard TTL, lower power than Schottky.","metaTitle":"54LS157FMQB Multiplexer, LS Series, Active, Bulk Package","metaDescription":"54LS157FMQB is an LS-series multiplexer from the 54LS family.
