Revised April 2003 NC7WZ241 TinyLogic UHS Dual Buffer with 3-STATE Outputs General Description Features The NC7WZ241 is a Dual Non-Inverting Buffer with 3-STATE outputs. The output enable circuitry is organized as active LOW for one buffer and active HIGH for the other buffer, thus facilitating transceiver operation. Space saving US8 surface mount package The Ultra High Speed device is fabricated with advanced CMOS technology to achieve superior switching performance with high output drive while maintaining low static power dissipation over a broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC operating range. The inputs and outputs are high impedance when VCC is 0V. Inputs tolerate voltages up to 5.5V independent of VCC operating range. Outputs tolerate voltages above VCC when in the 3-STATE condition. MicroPak leadless package Ultra High Speed; tPD 2.6 ns Typ into 50 pF at 5V VCC High Output Drive; 24 mA at 3V VCC Broad VCC Operating Range: 1.65V to 5.5V Matches the performance of LCX when operated at 3.3V VCC Power down high impedance inputs/outputs Overvoltage tolerant inputs facilitate 5V to 3V translation Outputs are overvoltage tolerant in 3-STATE mode Patented noise/EMI reduction circuitry implemented Ordering Code: Product Order Package Code Number Number Top Mark NC7WZ241K8X MAB08A NC7WZ241L8X (Preliminary) MAC08A WZ41 T7 Package Description Supplied As 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3k Units on Tape and Reel 8-Lead MicroPak, 1.6 mm Wide 5k Units on Tape and Reel TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.

The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. Note 2: The input and output negative voltage ratings may be exceeded is the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.

Note 6: C PD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD ) at no output loading and operating at 50% duty cycle. (See Figure 2.) CPD is related to ICCD dynamic operating current by the expression: ICCD = (CPD) (VCC) (fIN) + (ICC static). www.fairchildsemi.com 4 NC7WZ241 AC Loading and Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz, tw = 500 ns FIGURE 1.
