CD54AC573

The CD54AC573 octqal transparent 3-state lathces use the RCA ADVANCE CMOS technology.The outputs are transparent to the inputs when the latch Enable(LE) is HIGH.When the latch enable(LE) goes LOW,the data is lathced. CD54AC573 is supplied in 20-lead dual-in-line small-outline plastic packages(M suffix).Both package types are operable over the following temperature ranges:Commercial(0 to 70);industrial(-40 to +85);and extended industrial/military(-55 to +125).

Features of the CD54AC573 are:(1)exceeds 2-kv esd protection-MIL-STD-883,method 3015;(2)SCR-latchup-resistant CMOS process and circuit design;(3)speed of bipoiar FAST*/AS/S with significantly reduced power consumption;(4)balanced propagation delays;(5)AC types feature 1.5-V to 5.5-V operation and balanced noise immunity at 30% of the supply;(6)±24-mA output drive currentfanout to 15 FAST^*ICsdrives 50-ohm transmission lines.*fast is a reginstered trademark of fairchild semiconductor corp.

The absolute maximum ratings of the CD54AC573 can be summarized as:(1)CD54AC573 DC SUPPLY-VOLTAGE(V_CC):-0.5V to 6V;(2)DC INPUT DIODE CURRENT,IIK(for V_I<-0.5V or V_I>V_CC+0.5V):±20mA;(3)DC OUTPUT DIODE CURRENT,I_OK(for V_O<0.5V or V_O>V_CC+0.5V):±50mA;(4)CD54AC573 DC OUTPUT SOURCE OR SINK CURRENT per Output Pin,I_O(for V_O>-0.5V or V_OCC+0.5V):±50mA;(5)DC V_CC or GROUND CURRENT(I_CC orI_GND):±100mA^*;(6)CD54AC573 POWER DISSIPATION PER PACKAGE(P_D):For T_A=-55 to +100(PACKAGE TYPE E)-500mWFor T_A=+100 to +125(PACKAGE TYPE E)--derate lineraly at 8mW/ to 300mWFor T_A=-55 to +70(PACKAGE TYPE E)-400mWFor T_A=+70 to +125(PACKAGE TYPE E)--derate lineraly at 6mW/ to 70mW;(7)CD54AC573 OPERATING-TEMPERATURE RANGE(T_A):PACKAGE TYPE F...55 to +125PACKAGE TYPE E,M...-40 to +125;(8)STORAGE TEMPERATURE(T_stg):-65 to +150;(9)CD54AC573 LEAD TEMPERATURE(DURING SOLDERING):at distance 1/16±1/32 in.(1.59±0.79mm)from case for 10s maximum...+265unit inserted into PC board min.thickness 1/16 in.(1.59mm)with solder contacting lead tips only...+300.*For up to 4 outputs per device;add ±25mA for each additional output.
