Revised April 2003 NC7NZ34 TinyLogic UHS Triple Buffer General Description Features The NC7NZ34 is a triple buffer from Fairchild’s Ultra High Speed Series of TinyLogic in the space saving US8 package. 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 VCC range. The inputs and outputs are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC operating voltage. ■ Space saving US8 surface mount package ■ MicroPak leadless package ■ Ultra High Speed: tPD 2.4 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 ■ Power down high impedance inputs/outputs ■ Overvoltage tolerant inputs facilitate 5V to 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Product Order Package Code Number Number Top Mark NC7NZ34K8X MAB08A 7NZ34 NC7NZ34L8X (Preliminary) MAC08A P9 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. 250 mW Note 2: Unused inputs must be held HIGH or LOW. They may not float.
