3.3V CMOS 10-BIT BUFFERS Integrated Device Technology, Inc. IDT54/74FCT3827A/B FEATURES: * 0.5 MICRON CMOS Technology * ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) * 25 mil Center SSOP Packages * Extended commercial range of -40C to +85C * VCC = 3.3V 0.3V, Normal Range or VCC = 2.7V to 3.6V, Extended Range * CMOS power levels (0.4W typ. static) * Rail-to-Rail output swing for increased noise margin * Military product compliant to MIL-STD-883, Class B DESCRIPTION: The FCT3827A/B 10-bit bus drivers are built using an advanced dual metal CMOS technology. These high speed, low power buffers are ideal for high-performance bus interface buffering for wide data/address paths or buses carrying parity. The 10-bit buffers have NAND-ed output enables for maximum control flexibility. All of the FCT3827 high performance interface components are designed for high-capacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs.
