3 www.fairchildsemi.com MM74C154 Absolute Maximum Ratings(Note 1) Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. Except for “Operating Tempera- ture Range” they are not meant to imply that the devices should be oper- ated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation. Min/max limits apply across temperature range unless otherwise noted Voltage at Any Pin −0.3V to VCC + 0.3V Operating T emperature Range −40°C to +85°C Storage Temperature Range −65°C to +150°C Maximum V CC Voltage 18V Power Dissipation Dual-In-Line 700 mW Small Outline 500 mW Operating VCC Range 3V to 15V Lead Temperature (Soldering, 10 seconds) 260 °C Symbol Parameter Conditions Min Typ Max Units CMOS TO CMOS VIN(1) Logical “1” Input Voltage V CC = 5.0V 3.5 V VCC = 10V 8.0 V VIN(0) Logical “0” Input Voltage V CC = 5.0V 1.5 V VCC = 10V 2.0 V VOUT(1) Logical “1” Output Voltage V CC = 5.0V, IO = −10µA4 . 5 V VCC = 10V, IO = −10 µA9 . 0 V VOUT(0) Logical “0” Output Voltage V CC = 5.0V, IO = 10µA0 . 5 V VCC = 10V, IO = 10 µA1 . 0 V IIN(1) Logical “1” Input Current V CC = 15V, VIN = 15V 0.005 1.0 µA IIN(0) Logical “0” Input Current V CC = 15V, VIN = 0V −1.0 −0.005 µA ICC Supply Current V CC = 15V 0.05 300 µA CMOS TO LPTTL INTERFACE VIN(1) Logical “1” Input Voltage V CC = 4.75V V CC − 1.5 V VIN(0) Logical “0” Input Voltage V CC = 4.75V 0.8 V VOUT(1) Logical “1” Output Voltage V CC = 4.75V, IO = −100 µA2 . 4 V VOUT(0) Logical “0” Output Voltage V CC = 4.75V, IO = 360 µA0 . 4 V OUTPUT DRIVE (See Family Characteristics Data Sheet) (Short Circuit Current) ISOURCE Output Source Current V CC = 5.0V, VIN(0) = 0V −1.75 mA TA = 25°C, VOUT = 0V ISOURCE Output Source Current V CC = 10V, VIN(0) = 0V −8.0 mA TA = 25°C, VOUT = 0V ISINK Output Sink Current V CC = 5.0V, VIN(1) = 5.0V 1.75 mA TA = 25°C, VOUT = VCC ISINK Output Sink Current V CC = 10V, VIN(1) = 10V 8.0 mA TA = 25°C, VOUT = VCC
