IDT54/74FCT3244/A 3.3V CMOS OCTAL BUFFER/LINE DRIVER Integrated Device Technology, Inc. FEATURES: DESCRIPTION: • 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 and QSOP Packages • Extended commercial range of -40°C to +85°C • VCC = 3.3V ±0.3V, Normal Range or VCC = 2.7V to 3.6V, Extended Range • CMOS power levels (0.4µW typ. static) • Rail-to-Rail output swing for increased noise margin • Military product compliant to MIL-STD-883, Class B The FCT3244/A octal buffer/line drivers are built using advanced dual metal CMOS technology. These high-speed, low-power buffers are designed to be used as memory data and address drivers, clock drivers, and bus-oriented transmitter/receivers. The three-state controls are designed to operate these devices in a dual-nibble or single-byte mode. All inputs are designed with hysteresis for improved noise margin.
