MM54HCT112

The MM54HCT112 is designed as dual J-K flip-flop with preset and clear. this flip-flop utilize advanced silicon gate CMOS technology. It has input threshold and output drive similar to LS-TTL with the low standby power of CMOS.

MM54HCT112 has three features. (1)Typical propagation delay would be 20ns. (2)Low quiescent current would be 80uA maximum. (3)Fanout of 10 LS-TTL loads. Those are all the main features.

Some absolute maximum ratings about MM54HCT112 have been concluded into several points as follow. (1)Its supply voltage Vcc would be from -0.5V to 7V. (2)Its DC input voltage would be from -1.5V to Vcc+1.5V. (3)Its DC output voltage would be from -0.5V to Vcc+0.5V. (4)Its clamp diode current would be +/-20mA. (5)Its DC output current per pin would be +/-25mA. (6)Its DC Vcc or GND current per pin would be +/-50mA. (7)Its storage temperature range would be from -65°C to 150°C. (8)Its power dissipation would be 600mW and it would be 500mW fr SO package only. (9)Its lead temperature soldering 10 seconds would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to MM54HCT112.

Also some electrical characteristics of MM54HCT112 are concluded as follow. (1)Its maximum high level input voltage would be 2.0V. (2)Its maximum low level input voltage would be 0.8V. (3)Its minimum high level output voltage would be Vcc-0.1V at |Iout|=20uA and it would be 3.7V at Iout=4.0mA and Vcc=4.5V and it would be 4.7V at Iout=4.8mA and Vcc=5.5V. (4)Its maximum low level voltage would be 0.1V at |Iout|=20uA and it would be 0.4V at Iout=4.0mA and Vcc=4.5V and it would be 0.4V at Iout=4.8mA and Vcc=5.5V. (5)Its maximum input current would be +/-1.0uA. (6)Its maximum quiescent supply current would be 80uA at Vin=Vcc or GND and it would be 0.5mA at Vin=2.4V or 0.5V. And so on.
