TC74AC393F

The TC74AC393F is one member of the TC74AC393 series.The TC74AC393 is an advanced high speed CMOS 4-bit binary counter fabricated with silicon gate and double-layer metal wiring C2MOS technology.It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.It contains two independent counter circuits in one package, so that counting or frequency division of eight binary bits can be achieved with one IC.

Features of the TC74AC393F are:(1)high speed:fmax=180MHz(typ.) at Vcc=5V;(2)low power dissipation:Icc=8A(Max.) at Ta=25;(3)symmetrical output impedance:|IOH|=Iol=24mA(Min.) capability of driving 50 tansmission lines;(4)balanced propagation delays:tpLHtPHL;(6)wide operating voltage range:Vcc (opr)=2V~5.5V;(7)pin and function compatible with 74F393;(8)high noise immunity:Vnih=Vnil=28%Vcc(Min).The information contained herein is presented only as a guide for the applications of our products.No responsibility is assumed by TOSHIBA for any infringements of patents or other rights of the third parties which may result from its use. No license is granted by implication or otherwise under any patents or other rights of TOSHIBA or the third parties.

The absolute maximum ratings of the TC74AC393F can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)DC input voltage:-0.5 to Vcc+0.5V;(3)DC output voltage:-0.5 to Vcc+0.5V;(4)input diode current:±20mA; (5)output diode current:±50mA; (6)DC output current:±50mA; (7)DC Vcc/ground current:±200mA; (8)power dissipation:500mW; (9)storage temperature:-65 to 150.Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.Please contact your sales representative for product-by-product details in this document regarding RoHS compatibility.
