Description

The TC74ACT257P is designed as a high speed CMOS multiplexer fabricated with silicon gate C2MOS technology.

TC74ACT257P has six features. (1)High speed which would be typ 5.8ns at Vcc=5V. (2)Low power dissipation which means Icc=8uA max at Ta=25°C. (3)Compatible with TTL outputs which would be 0.8V max for low and 2.0V min for high. (4)Symmetrical output impedance which would be 24mA min. (5)Balanced propagation delays. (6)Pin and function compatible with 74F257. Those are all the main features.

Some TC74ACT257P absolute maximum ratings 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 TC74ACT257P characteristics at Vcc=4.5V are concluded as follow. (1)Its high level input voltage would be min 2.0V. (2)Its low level input voltage would be max 0.8V. (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.

TC74ACT257P 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.
