74ACTQ244

The 74ACTQ244 is an octal buffer and line driver designed to be employed as a memory address driver,clock driver and bus oriented transmitter or receiver which provides improved PC board density. The ACQ/ACTQ utilizes Fairchild Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance.FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.

The 74ACTQ244 is designed as one kind of octal buffer and line driver which designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver that provides improved PC board density.

Features of the 74ACTQ244 are:(1)faster prop delays than the standard AC/ACT244;(2)outputs source/sink 24 mA;(3)3-STATE outputs drive bus lines or buffer memory address registers;(4)improved latch-up immunity;(5)guaranteed pin-to-pin skew AC performance;(6)guaranteed simultaneous switching noise level and dynamic threshold performance;(7)Icc and IOZ reduced by 50%.

The absolute maximum ratings of the 74ACTQ244 can be summarized as:(1)supply voltage:-0.5V to +7.0V;(2)DC input diode current (VI=-0.5V):-20 mA;(3)DC input diode current (VI=VCC+0.5V):+20 mA;(4)DC input voltage:-0.5V to VCC+0.5V;(5)DC output diode current (VI=-0.5V):-20 mA;(6)DC output diode current (VI=VCC+0.5V):+20 mA;(7)DC output voltage:-0.5V to Vcc+0.5V;(8)DC output source or sink current of the 74ACTQ244:±50 mA;(9)DC Vcc or ground current per output pin:±50 mA;(10)storage temperature:-65°C to +150°C;(11)junction temperature PDIP:140°C;(12)DC latch-up source or sink current:±300 mA.If you want to know more information such as the electrical characteristics about it, please download the datasheet in www.seekic.com or www.chinaicmart.com .
