KK74HC161A Datasheet | Kodenshi AUK Group

TECHNICAL DATA Presettable Counters High-Performance Silicon-Gate CMOS The KK74HC161A is identical in pinout to the LS/ALS161. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The KK74HC161A is programmable 4-bit synchronous counter that feature parallel Load, asynchronous Reset, a Carry Output for cascading and count-enable controls. The KK74HC161A is binary counter with asynchronous Reset. - Outputs Directly Interface to CMOS, NMOS, and TTL - Operating Voltage Range: 2.0 to 6.0 V - Low Input Current: 1.0 µA - High Noise Immunity Characteristic of CMOS Devices LOGIC DIAGRAM ORDERING INFORMATION KK74HC161AN Plastic KK74HC161AD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT PIN 16 =VCC PIN 8 = GND FUNCTION TABLE Inputs Reset L H H H H H Load X L H H H X Enable P X X X L H X Enable T X X L X H X Clock X Q0 L P0 Outputs Q1 L P1 Q2 L P2 Q3 L P3 Function Reset to “0” Preset Data No count No count Count No count 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 ..net 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 Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±25 ±50 750 500 -65 to +150 260 Unit V V V m A m A m A m W °C °C Maximum Ratings are those values beyond which damage to the device may occur.
