3.3V CMOS 16-BIT BUFFER/LINE DRIVER IDT74FCT163244/A/C Integrated Device Technology, Inc. FEATURES: DESCRIPTION: • 0.5 MICRON CMOS Technology • Typical tSK(o) (Output Skew) < 250ps • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • Packages include 25 mil pitch SSOP, 19.6 mil pitch TSSOP and 15.7 mil pitch TVSOP • Extended commercial range of -40°C to +85°C • VCC = 3.3V ±0.3V, Normal Range or VCC = 2.7 to 3.6V, Extended Range • CMOS power levels (0.4µW typ. static) • Rail-to-Rail output swing for increased noise margin • Low Ground Bounce (0.3V typ.) • Inputs (except I/O) can be driven by 3.3V or 5V components The FCT163244/A/C 16-bit buffer/line drivers are built using advanced dual metal CMOS technology. These highspeed, low-power devices offer bus/backplane interface capability with improved packing density. These devices have a flow-through organization for simplifying board layout. The three-state controls operate these devices in a Quad-Nibble, Dual-Byte or single 16-bit word mode. All inputs are designed with hysteresis for improved noise margin. The inputs of the FCT163244/A/C can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V supply system. Thus, the FCT163244/A/C can be used as buffers to connect 5V components to a 3.3V bus.
