Description

The 74LS158 is a TTL-LS digital integrated circuit of the 54/74LS series of IPRS Băneasa: quad 2-to-1 line data selectors/multiplexers (inverted data outputs) [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the 54LS158 and 74LS158 (both marked as preliminary data), as quad 2-to-1 line data selectors/multiplexers (inverted data outputs) in an MP-117 package [1]. By the catalog’s table of families, the 74LS158 works at 0…+70 °C from a 4.75…5.25 V supply, and the 54LS158 at −55…+125 °C from 4.50…5.50 V [2].
