IDT54/74FCT373T/AT/CT FAST CMOS OCTAL TRANSPARENT LATCH MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL TRANSPARENT LATCH FEATURES: * * * * * * * * * IDT54/74FCT373T/AT/CT DESCRIPTION: Std., A, and C grades Low input and output leakage 1A (max.) CMOS power levels True TTL input and output compatibility: - VOH = 3.3V (typ.) - VOL = 0.3V (typ.) 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 permit "live insertion" Available in the following packages: - Industrial: SOIC, SSOP, QSOP, TSSOP - Military: CERDIP, LCC The FCT373Tis an octal transparent latch built using an advanced dual metal CMOS technology. These octal latches have 3-state outputs and are intended for bus oriented applications. The flip-flops appear transparent to the data when Latch Enable (LE) is high. When LE is low, the data that meets the set-up time is latched. Data appears on the bus when the Output Enable (OE) is low. When OE is high, the bus output is in the high-impedance state.
