Description

The 74LS174 is a TTL-LS digital integrated circuit of the 54/74LS series of IPRS Băneasa: hex D-type flip-flops (single-rail outputs, common direct clear) [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the 54LS174 and 74LS174 (both marked as preliminary data), as hex D-type flip-flops (single-rail outputs, common direct clear) in an MP-117 package [1]. By the catalog’s table of families, the 74LS174 works at 0…+70 °C from a 4.75…5.25 V supply, and the 54LS174 at −55…+125 °C from 4.50…5.50 V [2].
