Revised January 2001 NC7SZ125 TinyLogic UHS Buffer with 3-STATE Output General Description Features The NC7SZ125 is a single buffer with 3-STATE output from Fairchild’s Ultra High Speed Series of TinyLogic. The device is fabricated with advanced CMOS technology to achieve ultra high speed with high output drive while maintaining low static power dissipation over a very broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V range. ■ Space saving SOT23 or SC70 5-lead package The inputs and output are high impedance above ground when VCC is 0V. Inputs tolerate voltages up to 6V independent of VCC operating voltage. The output tolerates voltages above VCC when in the 3-STATE condition. ■ Power down high impedance inputs/output ■ 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 ■ Overvoltage Tolerant inputs facilitate 5V to 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Product Package Product Code Number Drawing Top Mark NC7SZ125M5 MA05B 7Z25 5-Lead SOT23, JEDEC MO-178, 1.6mm NC7SZ125M5X MA05B 7Z25 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZ125P5 MAA05A Z25 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 250 Units on Tape and Reel NC7SZ125P5X MAA05A Z25 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel Package Description Logic Symbol Supplied As 250 Units on Tape and Reel Connection Diagram IEEE/IEC (Top View) Pin Descriptions Pin Names Function Table Description Inputs Output A, OE Inputs OE In A Y Output L L L L H H H X Z Out Y H = HIGH Logic Level L = LOW Logic Level X = HIGH or LOW Logic Level Z = HIGH Impedance State TinyLogic is a trademark of Fairchild Semiconductor Corporation. © 2001 Fairchild Semiconductor Corporation DS012161 www.fairchildsemi.com NC7SZ125 TinyLogic UHS Buffer with 3-STATE Output October 1996 NC7SZ125 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 2) Supply Voltage (VCC ) −0.5V to +6V DC Input Voltage (VIN) −0.5V to +6V Supply Voltage Operating (VCC) DC Output Voltage (VOUT) −0.5V to +6V Supply Voltage Data Retention (VCC) DC Input Diode Current (IIK) 1.65V to 5.5V Input Voltage (VIN) @VIN < −0.5V −50 mA @ VIN > 6V +20 mA 1.5V to 5.5V 0V to 5.5V Output Voltage (VOUT) DC Output Diode Current (IOK) Active State 0V to VCC 3-STATE 0V to 5.5V @VOUT < −0.5V −50 mA Operating Temperature (TA) @ VOUT > 6V, VCC = GND +20 mA Input Rise and Fall Time (tr, tf) −40°C to +85°C DC Output Current (IOUT) ± 50 mA VCC = 1.8V, 2.5V ± 0.2V 0 ns/V to 20 ns/V DC VCC/GND Current (ICC/IGND) ± 50 mA VCC = 3.3V ± 0.3V 0 ns/V to 10 ns/V −65°C to +150 °C VCC = 5.0V ± 0.5V 0 ns/V to 5 ns/V Storage Temperature (TSTG) 150 °C Junction Temperature under Bias (TJ) Thermal Resistance (θJA) Junction Lead Temperature (TL); 260 °C (Soldering, 10 seconds) Power Dissipation (PD) @ +85°C SOT23-5 200 mW SC70-5 150 mW SOT23-5 300°C/W SC70-5 425°C/W 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: Unused inputs must be held HIGH or LOW. They may not float.

(See Figure 2.) CPD is related to ICCD dynamic operating current by the expression: ICCD = (C PD)(VCC)(fIN) + (ICCstatic).
