DescriptionThe 74ACT161SCX is one member of the 74ACT161SCX family which is designed as high-speed CMOS SYNCRONOUS PRESETTABLE COUNTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. The circuit have four fundamental modes of operation, in order of preference: synchronous reset, parallel load, count-up and hold. Four control inputs, Master Reset (CLEAR), Parallel Enable Input (LOAD), Count Enable Input (PE) and Count Enable Carry Input (TE), determine the mode of operation as shown in the Truth Table.
Features of the 74ACT161SCX are:(1)Highspeed:fMAX =125MHz (TYP.) atVCC =5V; (2)Lowpower dissipation:ICC =8A (MAX.) at TA =25 oC; (3)High noise immunity:VNIH=VNIL =28%VCC (MIN.); (4) transmission linedriving Capability; (5) Symmetrical output impedance:|IOH| = IOL = 24mA (MIN); (6)Balance dprop agationde lays:tPLH @ tPHL; (7)Operatingvoltagerange:VCC (OPR)=4.5V to 5.5V; (8) Pinand function compatible with 74 SERIES161; (9)Improvedlatch-up immunity.
The absolute maximum ratings of the 74ACT161SCX can be summarized as:(1)supply voltage:0.5-7V;(2)DC Input Voltage:-0.5 to Vcc +0.5V;(3)iDC Output Voltage:-0.5 to Vcc +0.5V;(4)DC Input Diode Current:±20 mA;(5)DC OutputDiode Current:±20 mA;(6)DC OutputCurrent:±50 mA;(7)DC VCC or Ground Current:±300mA;(8)storage temperature:-65°C to +150°C;(9)Lead Temperature (10 sec):300°C.
