IDT74FCT163374/A/C 3.3V CMOS 16-BIT REGISTER (3-STATE) 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 FCT163374/A/C 16-bit edge-triggered D-type registers are built using advanced dual metal CMOS technology. These high-speed, low-power registers are ideal for use as buffer registers for data synchronization and storage. The Output Enable (xOE) and clock (xCLK) controls are organized to operate each device as two 8-bit registers or one 16-bit register with common clock. Flow-through organization of signal pins facilitates ease of layout. All inputs are designed with hysteresis for improved noise margin. The inputs of FCT163374/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.
