Description
The NC7SZ34 is a single buffer from Fairchild’s Ultra-
High Speed (UHS) 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 broad
VCC operating range of 1.65V to 5.5V VCC. The inputs
and output are high-impedance when VCC is 0V. Inputs
tolerate voltages up to 7V, independent of VCC operating
voltage.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Note:
2. CPD is defined as the value of the internal equivalent capacitance derived from dynamic operating current
consumption (ICCD) at no output lading and operating at 50% duty cycle. CPD is related to ICCD dynamic operating
current by the expression: ICCD=(CPD)(VCC)(fIN)+(ICCstatic).
