KK74ACT253 Datasheet | Kodenshi AUK Group

TECHNICAL DATA .. Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Speed Silicon-Gate CMOS The KK74ACT253 is identical in pinout to the LS/ALS253, HC/HCT253. The KK74ACT253 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The Address Inputs select one of four Data Inputs from each multiplexer. Each multiplexer has an active-low Output Enable control and a three-state noninverting output. - TTL/NMOS patible 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 m A ORDERING INFORMATION KK74ACT253N Plastic KK74ACT253D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs A1 X L L H PIN 16 =VCC PIN 8 = GND H A0 X L H L H Output Enable H L L L L Output Y Z D0 D1 D2 D3 D0,D1...D3=the level of the respective Data Input Z = high impedance X = don’t care ..
