74FCT163827A/C 3.3V CMOS 20-BIT BUFFER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 20-BIT BUFFER 74FCT163827A/C FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT163827 20-bit buffer is built using advanced dual metal CMOS Typical tSK(o) (Output Skew) < 250ps technology. These 20-bit bus drivers provide high-performance bus ESD > 2000V per MIL-STD-883, Method 3015 > 200V using interface buffering for wide data/address paths or busses carrying parity. machine model (C = 200pF, R = 0) Two pairs of NAND-ed output enable controls offer maximum control VCC = 3.3V 0.3V, Normal Range, or VCC = 2.7V to 3.6V, Extended flexibility and are organized to operate the device as two 10-bit buffers or Range one 20-bit buffer. Flow-through organization of signal pins simplifies layout. CMOS power levels (0.4 W typ. static) All inputs are designed with hysteresis for improved noise margin. Rail-to-rail output swing for increased noise margin The FCT163827 has series current limiting resistors. This offers low Low Ground Bounce (0.3V typ.) ground bounce, minimal undershoot, and controlled output fall times, Inputs (except I/O) can be driven by 3.3V or 5V components reducing the need for external series terminating resistors. Available in TSSOP package The inputs of the FCT163827 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.
