3.3V CMOS 16-BIT BUS TRANSCEIVER/ REGISTERS IDT74FCT163646/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 FCT163646/A/C 16-bit registered transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independant 8-bit bus transceivers with 3-state D-type registers. The control circuitry is organized for multiplexed transmission of data between A bus and B bus either directly or from the internal storage registers. Each 8-bit transceiver/register features direction control (xDIR), over-riding Output Enable control (xOE) and Select lines (xSAB and xSBA) to select either real-time data or stored data. Separate clock inputs are provided for A and B port registers. Data on the A or B data bus, or both, can be stored in the internal registers by the LOW-to-HIGH transitions at the appropriate clock pins. Flowthrough organization of signal pins simplifies layout. All inputs are designed with hysteresis for improved noise margin. The FCT163646/A/C have series current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times-reducing the need for external series terminating resistors.
