Revised March 2001 NC7WZ126 TinyLogic UHS Dual Buffer with 3-STATE Outputs General Description Features The NC7WZ126 is a Dual Non-Inverting Buffer with independent active HIGH enables for the 3-STATE outputs. 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. ■ Space saving US8 surface mount 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: Order Package Package Number Number Top Mark MAB08A WZ26 NC7WZ126P8X Package Description Supplied As 8-Lead US8, 0.7mm x 3.1mm x 2.0mm Logic Symbol 3k Units on Tape and Reel Connection Diagram (Top View) Pin Descriptions Function Table Pin Names Description OEn Enable Inputs for 3-STATE Outputs OE Inputs An Output An Inputs H L L Yn 3-STATE Outputs H H H L L Z L H Z Yn H = HIGH Logic Level L = LOW Logic Level Z = 3-STATE TinyLogic is a trademark of Fairchild Semiconductor Corporation. © 2001 Fairchild Semiconductor Corporation DS500397 www.fairchildsemi.com NC7WZ126 TinyLogic UHS Dual Buffer with 3-STATE Outputs March 2001 NC7WZ126 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 3) Supply Voltage (VCC ) −0.5V to +7.0V DC Input Voltage (VIN) (Note 2) −0.5V to +7.0V Supply Voltage Operating (VCC) DC Output Voltage (VOUT) −0.5V to +7.0V Supply Voltage Data Retention (VCC) DC Input Diode Current (IIK) 1.65V to 5.5V 1.5V to 5.5V Input Voltage (VIN) @VIN < 0V −50 mA DC Output Diode Current (IOK) @VOUT < 0V −50 mA ±50 mA DC Output Source/Sink Current (IOUT) +150 °C Junction Lead Temperature (TL) +260 °C (Soldering, 10 seconds) 0V to VCC 0V to 5.5V −40°C to +85°C Input Rise and Fall Time (tr, tf) −65°C to +150 °C Storage Temperature Range (TSTG) Junction Temperature under Bias (TJ) Active State 3-State Operating Temperature (TA) ±100 mA DC VCC/GND Current (ICC/IGND) 0V to 5.5V Output Voltage (VOUT) VCC = 1.8V, 0.15V, 2.5V ± 0.2V 0 ns/V to 20 ns/V VCC = 3.8V ± 0.3V 0 ns/V to 10 ns/V VCC = 5.0V ± 0.5V 0 ns/V to 5 ns/V Thermal Resistance (θJA) Power Dissipation (PD) @+85°C 250°C/W SC70-6 SC70-6 250 mW Note 1: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. 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: CPD 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) (V CC) (fIN) + (ICC static). 3 www.fairchildsemi.com NC7WZ126 AC Loading and Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz, tw = 500 ns FIGURE 1.
