HD74LS157 Quadruple 2-line-to-1-line Data Selectors / Multiplexers (noninverted outputs) REJ03D0442–0200 Rev.2.00 Feb.18.2005 This data selector / multiplexer contains inverters and drivers to supply full on-chip data selection to the four output gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. Then, outputs present true data to minimize propagation delay time.
