IN74ACT163

TECHNICAL DATA IN74ACT163 Presettable Counters High-Speed Silicon-Gate CMOS The IN74ACT163A is identical in pinout to the LS/ALS163 HC/HCT163. The IN74ACT163 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed Cmos Inputs. The IN74ACT163A is programmable 4-bit synchronous counter that feature parallel Load, synchronous Reset, a Carry Output for cascading and count-enable controls. The IN74ACT163A is binary counter with synchronous Reset. 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 mA @25°C Ouptuts Source/Sink 24mA ORDERING INFORMATION IN74ACT163N Plastic IN74ACT163D SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 16 =VCC PIN 8 = GND Inputs Reset L H H H H Load X Enable P X X X L H X FUNCTION TABLE Outputs Enable T X X L X H X Clock Q0 L P0 Q1 L P1 Q2 L P2 Q3 L P3 Function Reset to “0” Preset Data No count No count Count No count w w w .d h s a t a ee X . u t4 m o c L H H H X No change No change Count up No change X=don’t care P0,P1,P2,P3 = logic level of Data inputs Ripple Carry Out = Enable T Q0 Q1 Q2 Q3 1 www.DataSheet4U.com IN74ACT163 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Curren...
