KK74HCT20A
KK74HCT20A is Dual 4-Input NAND Gate manufactured by Kodenshi AUK Group.
TECHNICAL DATA Dual 4-Input NAND Gate High-Performance Silicon-Gate CMOS The KK74HCT20A is identical in pinout to the LS/ALS20. The KK74HCT20A may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. - 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 - High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HCT20AN Plastic KK74HCT20AD SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT NC = NO CONNECTION PIN 14 =VCC PIN 7 = GND PINS 3,11 = NO CONNECTION FUNCTION TABLE Inputs A L X X X H B X L X X H C X X L X H D X X X L H Output Y H H H H L X = don’t care ..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.
