SL74HCT20

SL74HCT20 Dual 4-Input NAND Gate High-Performance Silicon-Gate CMOS The SL74HCT20 is identical in pinout to the LS/ALS20. The SL74HCT20 may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. 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 High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HCT20N Plastic SL74HCT20D 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 SLS System Logic Semiconductor SL74HCT20 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 mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.
