IDT54/74FCT573T/AT/CT FAST CMOS OCTAL TRANSPARENT LATCH MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL IDT54/74FCT573T/AT/CT TRANSPARENT LATCH FEATURES: DESCRIPTION: Std., A, and C grades The FCT573Tis an octal transparent latch built using an advanced dual Low input and output leakage 1A (max.) metal CMOS technology. These octal latches have 3-state outputs and are CMOS power levels intended for bus oriented applications. The flip-flops appear transparent to True TTL input and output compatibility: the data when Latch Enable (LE) is high. When LE is low, the data that meets VOH = 3.3V (typ.) the set-up time is latched. Data appears on the bus when the Output Enable VOL = 0.3V (typ.) (OE) is low. When OE is high, the bus output is in the high-impedance state. High Drive outputs (-15mA IOH, 48mA IOL) Meets or exceeds JEDEC standard 18 specifications Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permitlive insertio Available in the following packages: Industrial: SOIC, QSOP Military: CERDIP, LCC FUNCTIONAL BLOCK DIAGRAM D2 D3 D6 D7 D0 D1 D4 D5 D D D D D D D D O O O O O O O O G G G G G G G G LE OE O0 O1 O2 O3 O4 O5 O6 O7 IDT and the IDT logo are registered trademarks of Integrated Device Technology, Inc.
