No Preview Available ! TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS IN74ACT158 The IN74ACT158 is identical in pinout to the LS/ALS138, HC/HCT138. The IN74ACT158 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in invertered form. A high level on the Output Enable input sets all four Y outputs to a high level. • TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 4.5 to 5.5 V • Low Input Current: 1.0 µA; 0.1 µA @ 25°C • Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT158N Plastic IN74ACT158D SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 16 =VCC www.datasheet4u.PcINo8m= GND FUNCTION TABLE Inputs Outputs Output Enable Select Y0-Y3 H XH L L A0-A3 L H B0-B3 X=don’t care A0-A3,B0-B3=the levels of the respective Data-Word Inputs 1 1 page IN74ACT158 EXPANDED LOGIC DIAGRAM A0 B0 A1 B1 A2 B2 A3 B3 OE SELECT Y0 Y1 Y2 Y3 5 5 Page
