TC74AC20P

The TC74AC20P is designed as a high speed CMOS 4-input NAND gate fabricated with silicon gate C2MOS technology.

TC74AC20P has six features. (1)High speed which would be typ 4.1ns at Vcc=5V. (2)Low power dissipation which means Icc=4uA max at Ta=25°C. (3)High noise immunity 28% Vcc min. (4)Symmetrical output impedance which would be 24mA min. (5)Balanced propagation delays. (6)Pin and function compatible with 74F20. Those are all the main features.

Some absolute maximum ratings of TC74AC20P have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 7.0V. (2)Its DC input voltage would be from -0.5V to Vcc+0.5V. (3)Its DC output voltage would be from -0.5V to Vcc+0.5V. (4)Its input diode current would be +/-20mA. (5)Its output diode current would be +/-50mA. (6)Its DC output current would be +/-50mA. (7)Its DC Vcc/ ground current would be +/-100mA. (8)Its power dissipation would be 500mW. (9)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some DC electrical characteristics about TC74AC20P at Vcc=4.5V are concluded as follow. (1)Its high level input voltage would be min 3.85V. (2)Its low level input voltage would be max 1.65V. (3)Its high level output voltage would be min 4.4V and typ 4.5V at Ioh=-50uA. (4)Its low level output voltage would be max 0.1V at Iol=50uA.

TC74AC20P should be noted that toshiba is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the users, when utilizing these products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a product could cause loss of human life, bodily injury or damage to property.
