Revised June 2003 NC7WZ125 TinyLogic UHS Dual Buffer with 3-STATE Outputs General Description Features The NC7WZ125 is a Dual Non-Inverting Buffer with independent active LOW 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 ■ 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 NC7WZ125K8X MAB08A NC7WZ125L8X Package Description WZ25 MAC08A Supplied As 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3k Units on Tape and Reel P3 8-Lead MicroPak, 1.6 mm Wide Logic Symbol 5k Units on Tape and Reel Connection Diagrams IEEE/IEC Pin Descriptions Pin Names Description OEn Enable Inputs for 3-STATE Outputs (Top View) An Input Pad Assignments for MicroPak Yn 3-STATE Outputs Function Table Inputs Output OE An L L L L H H H L Z H H = HIGH Logic Level Yn H Z L = LOW Logic Level Z = 3-STATE TinyLogic is a registered trademark of Fairchild Semiconductor Corporation. © 2003 Fairchild Semiconductor Corporation DS500396 (Top Thru View) MicroPak is a trademark of Fairchild Semiconductor Corporation. www.fairchildsemi.com NC7WZ125 TinyLogic UHS Dual Buffer with 3-STATE Outputs March 2001 NC7WZ125 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 3) Supply Voltage (VCC) −0.5V to +7V DC Input Voltage (VIN) (Note 2) −0.5V to +7V Supply Voltage Operating (VCC) DC Output Voltage (VOUT) −0.5V to +7V 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) Power Dissipation (PD) @ +85°C 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 Lead Temperature under Bias (TJ) Active State 3-STATE Operating Temperature (TA) ± 100 mA DC VCC/Ground 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 @ 3.3V ± 0.3V 0 ns/V to 10 ns/V VCC @ 5.0V ± 0.5V 0 ns/V to 5 ns/V Thermal Resistance (θJA) 250°C/W 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 if 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 = (C PD)(VCC)(fIN) + (ICCstatic). 3 www.fairchildsemi.com NC7WZ125 AC Loading and Waveforms CL includes load and stray capacitance Input PRR = 1.0 MHz; tw = 500 ns FIGURE 1.
