IN74HCT163A

TECHNICAL DATA IN74HCT163A Presettable Counters High-Performance Silicon-Gate CMOS The IN74HCT163A is identical in pinout to the LS/ALS163. The IN74HCT163 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The IN74HCT163A is programmable 4-bit synchronous counter that feature parallel Load, synchronous Reset, a Carry Output for cascading and count-enable controls. The IN74HCT163A 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 ORDERING INFORMATION IN74HCT163AN Plastic IN74HCT163AD SOIC TA = -55° to 125° 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 IN74HCT163A 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 Current, per Pin DC Supply Current, VCC and GND Pins Power ...
