1 U74ACT157 UNISONIC TECNOOGIES CO., TD QUADRUPE 2-INE TO 1-INE DATA SEECTOR/ MUTIPEER DESCRIPTION The U74ACT157 is a quadruple 2-line to 1-line data selector/multiplexer. When G is high, all outputs are low. When G is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The devices provide true data. FEATURES * TT-Voltage Compatible * Max t PD of 4.1 from A or B to Y at 5V, C =15pF * ow Quiescent Current: I CC = 2 μa (MA) at 5.5V * ±8 ma output driver at 5V ORDERING INFORMATION Ordering Number ead Free alogen Free Package Packing U74ACT157-P16-R U74ACT157G-P16-R TSSOP-16 Tape Reel U74ACT157-P16-T U74ACT157G-P16-T TSSOP-16 Tube 1 of 6 Copyright 2011 Unisonic Technologies Co., td
